Check if GMLive_thread script has any code in it - there is a bug with GMS2.3 where it may sometimes clear a file instead of replacing the contents.
GMLive_thread
ah, you're right, there isn't should i try re-importing it?
Yeah - or extract the YYMPS with 7-zip and manually copy-paste the GML code into the script.
i'm sorry how would i manually import the code?
Open the extracted GML file with any text editor, copy everything, paste into the same-named script in GMS2 IDE.
