Okay, now having played around in the hub for a bit, I can say a few things about this update.
To start, the really good part. The hub looks amazing now. There seems to be some overlap of characters, but otherwise this new hub is way more interesting than the original. Also, the new scenes are a nice addition.
Now for the issues. Bugs. There's a lot of them. I'll break down the ones I've found in the hub.
1. Every scene in the hub I've found has the same bug: if you let the meter fill on a scene, a new scene will start while the other is still going, creating a very laggy overlap of two scenes going simultaneously. The only way I've found to get rid of this bug is to end the scene entirely.
2. Sometimes ending a scene will result in a bug where it tries to load in the map, fails, tries again, fails, loop. The only way to end this bug is to restart, and if this bug triggers you have to start a new game.
3. Save game bug. Going to the bottom floor and claiming your equipment can be negated by saving the game, resulting in you losing all of the equipment the quartermaster gave you. You can get it back, but I believe this plays into the next bug.
4. Unable to enter Ghost Frontier. It may be because I tried to save and triggered the save game bug, but the carriage sister just keeps repeating that I need gear for three days, even if I already got gear from the quartermaster.
Will update once I get into the Frontier.
Update: Just got her to trigger the Carriage Awaits quest and finally saw that the Frontier is currently unavailable. I am definitely excited to see the Frontier next update, but I can wait. I do think the failure to trigger the Carriage Awaits quest was due to the save game bug, as not saving prevented the issue.
I will post some small bugs I noticed. Hope this helps.
1. Chests can be repeatedly opened, allowing you to get infinite tokens.
2. The sister that brings you to the Priestess will begin following you again if you talk to her after talking to the Priestess.
3. The new scenes are phenomenal, but there is a tiny bit of clipping at times. No big deal, but figured I'd point it out just to be safe.
I think that's all I have found.
