This is really strange. Just for curiosity, did you start from a saved game? I wonder if it's a problem of the save states. Unfortunately it's not possible to export the saved games from the web local storage, so I'll have to review the code to check how this could be possible (or at least add some double checks)

I spent several hours debugging, but I could not find the problem. Have you tried the Windows (or Mac) version? Maybe it's a bug in the web engine. If you want, join the discord server so we can communicate faster: https://discord.gg/2dRncccJ5A Thanks!
