Will be fixed in next update. Thank you.

Took me awhile to figure this out, but I'm getting the same.

I'm glad you're looking into it. Otherwise, this mod is great and I really do love the interaction it provides. Would you mind making a post here when you've updated it? I'll subscribe to this discussion so I can get the update. I would greatly appreciate it!

Oh, also, this one happens during a risk but not necessarily a full break. It's not a 10jobs in 1 tick, but it's a reference to a null value.

It was happening while teaching(teaching mod).

log here:

Pretty sure that no one tries to debug using these, everyone uses the debug log instead.
This one is more of the Unity side that Tynan would use to debug his assemblies or something.

Busy with real life and the likes. Update >hopefully< coming this Friday.

Update in about an hour.

You're a boss!

Updated.
