I had a couple of goblins ( the plain green kind, kinda like the ‘workers’ of goblin-kind) raid my camp and my footmen went after them. But I noticed, while the goblins were running away with my footmen on their tails, they (the goblins) kept getting the yellowish particle effects (like what happens during an attack), but were not sustaining any damage.
They did eventually die, but it wasn’t until they stopped moving and cowered against a cliff wall with my footmen attacking, that their ‘hearts’ went down. My guys were using stone hammers, so they should have gone down quickly.
I’m using the latest unstable build (  ), steam client.
