Hi! Firstly, let me second what TideSlayer said about the incredible work on this game. After years of thinking I'd never get to play islands like my beloved Astro-Knights again, it's great that I have that option restored to me.
Secondly, though, I'm having a similar issue to the one described here (similar enough that I opted to post about it in the same thread, but I apologize if I should have started a new one instead). Unlike for TideSlayer, however, hitting "Save & Quit" doesn't resolve the issue for me.
The problem I'm having is that when I create a new profile, it doesn't ever seem to save it. I'll create the character, customize the name and appearance to what I want, and then click "Enter Poptropica," at which point I start the game. I can play it fine, but then when I'm done, I'll click "Save & Quit" in the menu, and the game will close. If I then open it back up and click "Returning Player," there's no trace of the character I created previously.
I guess that's not actually surprising, though, because at no point while creating that character did the game prompt me to create a username or password, so of course there's no way for me to log in to that character again; it was never saved as a profile in the first place. So basically, I'm creating a character, but not a profile. I've tried it several times and haven't noticed any option to input the profile info. It's possible I'm just blind, but as far as I can tell, it's not there. Which means anytime I make a new character and then quit out of the game (regardless of whether I hit "Save" or not), the character is lost forever.
Notably, this issue doesn't happen for imported profiles. But I want to start from scratch with a new one, which I'm not currently able to do. I guess I could technically create a new profile on the CoolMath version of Poptropica, save it, and then use that (I've tested it and it does work), but I don't want to do that because the CoolMath version of the game doesn't seem to give you the option to customize your name and appearance while creating your character.
I know you've probably got a million bugs and updates to work through on this, so no rush! But I just wanted to let you know it's happening so you can get to it in your own time (and just in case I'm missing an obvious fix you could point me to.)
And finally, apologies again if this should have been its own thread.
