I'm having a problem with sprites and backgrounds not appearing in any room and was told is was likely a firewall thing in an antivirus. I have Avast. What settings should I change to allow GMS2 to work properly?
So that mostly fixed the problem, but some files done in previous versions of GMS2 still have this problem. This is after I went through each runtime version added allow app for Igor.exe for every runtime version there.
