So I have steam subsystem set up in my project. I’ve got my steam app id for my game implemented into the DefaultEngine.ini as expected. I have play-tested matchmaking several times with no problems. Creating sessions and even joining them. Well ever since I packaged my game I can no longer create sessions in either the packaged game or my standalone PIE… I just spent 4 hours debugging and testing a different problem I had that was caused from packaging my game… I feel like everything in my game is now messed up just from packaging it. Why is this a thing?
try to disable your antivirus/firewall and having Steam open/close if that does any change.
Disabled Antivirus, Disabled Firewall and Opened / Closed Steam. All failing to create session. Where as before I packaged the game, I could launch Standalone and create sessions no problem. I don’t get the issue here.
I found the solution. For some reason after packaging my game one of the nodes connecting to my “Create Session” node that parses “Extra Settings” data got corrupted. I had to go into that macro and recompile it. It now works again… Seems like a really ridiculous bug to have in a game engine. Luckily my game isn’t too complex yet.
