I'm noticing that the small bale collection point for the barn is really rather small. Like, one square meter, small. Is that normal, or am I missing something?
Are you using Realistic Weather, by chance? If so, try without it. The crash every five minutes lines up with the moisture check that the mod performs.
I do believe that Realistic Weather is the current culprit that is giving people freeze/crash issues. At the very least, it seems to be responsible for mine.
