So basically, whenever I try to app_update 4020, it goes on downloading like normal, but ends with this error code:
Error! App ‘4020’ state is 0x602 after update job.
This also happens when I try app_update 4020 validate
If it has anything to do with it - my stupid antivirus software deleted a huge section of code in my server including everything attached to it. Which also broke my gmod. Please help, I spent a lot of time getting my server the way I wanted it.
