Hello ,
Im not sure where to put this error but the forum name matches the error type. So i was also messing around in sandbox to see if i run into any issues with mod compatibility when this happend. I was using the Warden vechile from AAI vechiles pack(link at bottom) and ran over a biter then i crashed with the folowing report.
The mod RPG System (1.1.9) caused a non-recoverable error.
Please report this error to the mod author.
