Windows 3.10. I bought the game yesterday. I redownloaded it today, and I am still getting those error messages.
Okay, i double check and even upload a new Win/Linux and Mac version (V3.11 now). For some reason this error is the missing asset of the Hide interface button.Start a new game with this version instead of load any save please!
So, my programmer is saying to download the new version, and make sure not to play from any old save points you have.
It is fixed now, thank you!
