Hey I'm running windows, freshly installed the metamod and sourcemods. The gamedata file is in its place. The smx file is in its place. No cvars even messed with. It keeps randomly crashing in the beginning of maps, i've tested with first map of parish and first map of dark carnival.
It keeps putting this in the log...

which doesn't really tell me much, it's not even noticing that it is crashing since the game crashes a couple minutes after these reports. I think I can link it to the SI spawning. This is done in coop mode, solo.
I just cleared it twice, and now i dont even get as much in the log as i was getting

Other random tidbits...

The crashing problem immediately goes away upon disabling this addon as well.
