I encountered an error upon arriving at the Pyramid near Neko Village. I can click Retry to make it go away, but it just comes back after a few seconds. Not to mention, but the background music doesn't play upon entering. Here's a screenshot. 
It's quite a well known bug in here. This is strangely the only area that does this, and I'm guessing they forgot to change a bit of the code to reference the rpgmvo file that is the exact same.
There are two fixes to it: a temp solution and a tested solution that is reliable (until the next update that is.)
Reliable solution:
To fix it, find in the audio folder bgm, and find two files that state "El Infausto Landron de Joyas A.rpgmvo" and "El Infausto Landron de Joyas B.rpgmvo"
You'll want to copy them (just in case of corruption) and change the names respectively to "El Infausto Landron de Joyas A.ogg" and "El Infausto Landron de Joyas B.ogg"
Temp Solution:
You can do what I did first time playing it, which was spam the enter key until I got to the underground section, save the game, and refreshed the game. That also seemed to work as a fix.
Unfortunately renaming them didn't work for me, for some reason. As an additional temp solution, go to google and play some desert music on youtube, and spam enter at all times in the area until reaching the underground section . I've found the Super Mario Bros. DS desert level theme works best with fetish games for maximum immersion.
Reliable fix found a little further back in this report page can confirm fixed immediately.
first go into the game files and find folder www, then Audio, then bgm. Find El Infausto Ladron de Joyas. There should be two files: A and B.
Now remane Ladron to Ladrón for both. Thanks Shidoy
i thought i made a comment somewhere around here about that. the solution i found was that a file was misnamed, so you'll have to go into the files and rename it to that. as i recall, it was capitalizing the A at the end, or something...
Edit: ah, thaaaat's right, i remember now... "not sure if anyone posted this yet, but the game keeps stopping during the pyramid. i had to change a file to "El Infausto Ladrón de Joyas A.rpgmvo", notice the "ó" in "Ladrón""
I just went through the mansion and defeated the bad guy, repaired the basement after giving some spirits and I fell into a demon temple, the game crashes after a few seconds and I haven't been able to get out by any means. I beg for your help, please, I was enjoying the game a real lot but I don't know what to do now.
We encountered the same problem:
The file can be reached using similar replacement, but this will cause image errors.
Not only the triplets mission, but also after the main story ends.
I guess this location is definitely not finished. The giant tree monster, the fairy kingdom, and the cave in the forest cannot be reached. Similarly, some old maps are not completed.
Due to the hard bug, many people no longer talk to me. You can check one village at a time.
Soft lock warning: Don't talk to people such as the dragon messenger. If you inherit the archive,You will be transferred to the dark map and soft locked.
In addition to this, if you do give the girl the second seed, she will ask for a third seed. If you refuse the third seed, the question will loop. If you give it to her, her final dialogue for the third seed will loop. Interacting with her after giving her a seed will softlock no matter what you do.
I found a fix for both.
1: Copied that map from v410 and pasted over it in v501
2: Deleted Event Page 5 form the event in RPG Maker then transferred the edited map from there into the game file.
A) Open the game up in RPG Maker.
B) Go to Map 276 (foreste ruin) and Map 282 (foreste Fixed Ruins outside).
C) Go to Event 004 on square 34.49, go to the 5th tab (which was empty) and click "Delete Event Page" then "Apply" and "Save Project".
D) Go to the Game files on the RPG Maker in "Data" and copy the "Map276.json" and "Map 282.json" files and paste over them in the regular game file www\data. (I would recommend you make a back up copy of the original unedited map files somewhere before pasting over them.)
Despite the scary-looking syntax error, it looks like it’s basically just an out-of-bounds map transfer. The map it attempts to load is a blank parent to a sub-map for a specific basement scene, which seems to set a flag that doesn’t get checked anywhere else and also transfers the player right back to the same blank map rather than back to the basement entrance.
For now it seems the best workaround is to just ignore the stairs, but since it’s an unrecoverable error that forces the player to reload the game, it should definitely be a priority for fixing or removing for the next patch.
Hi. In version 501, in Witch Academy, in game by Valorie at night, in first level of academy, where classes. In this room ladder to basement. An error occurred when entering. The game doesn't respond to anything else.
I had an issue with the slime quest, i went back to that area and got soft locked because I can leave the area
Not sure if this is a common issue or not. I'm in the middle of the quest where you ask the goddess to appear in court (idk what the quest is called as I can't view any of my quests except like one of the still active side quests, they all just disappeared at some point so I'm kinda running around blind and aimless rn). I just talked to her, finished the convo and am at the point where I'm able to move again but her character image is stuck on the screen. i tried saving, exiting the game entirely, booted it back up, but she's still in the way. not sure how to fix this aside from reverting to a previous save. however, I'm worried that if I try to redo this leg of the quest that she's just gonna get stuck again. not sure what to do here (sorry, I'm not super tech savvy).
I can't seem to get rid of her and she takes up half the screen. :/
Not sure why I can't view the main or character quests.
Current main quests I've done up until this point.
It happened when I talked to the log elf
When I try to go to the basement in the witch academy on the apprentice side, I get this error and it doesn't let me do anything after that until I close the game.
