Alright, looks like even after removing the bugfixes extension the crashes still sort of happen.
Although, they seem to occur only during loading a new campaign after a few campaigns have been played instead of random points in time now.
Something I'll admit I was reluctant to mention is that my Sourcemod plugins are also mostly different to the main thread, so I don't think anyone else had the same problems as mine...
Here's the latest crash log I have of this, both the
Throttle URL and attachment.
