[H3SW v0.8.0] Upgrade goblin glitch?

The error say, "it should not been happen, but it happened". Like that. So, I upload this crash log to you just in case if you are interested.

Edit: I can't describe properly because it just happen randomly and suddenly without any noticing. After loading the same game, it back to normal without this crash.

So instead I post a glitch that I can describe properly.
It somehow having a "goblin barbarian sound" when I kill this gltch/creature?

I cannot do anything about this bug until you describe what happened, what did you do, and likely post a link to a savegame here.

Check my new OP.

I need a savegame. From your explanation, I cannot understand the problem.

That bug is from an out-dated version of the "Gelea's Champions" map. The bug is already fixed in the upcoming release
