Android 14 is what I've been testing on mostly. The error I thought was with the rpg_manager.js file, which is just part of the engine, as far as I could tell.
Okay then. I didn't had that problem. Except for the saving, which I didn't test extensivily. Everything else just worked out of the box with exceptions already mentioned. I'll test with android 14 too.
Thanks for reporting back. I'm gonna search for a solution!
