0001978: Ant mounds and bee hives appear in stone and ice (even after waterways thaw)
Not sure if the placement of ant mounds is tied to the actual raw creature file for ants, but the mounds are being placed where they shouldn't appear, namely in stone and ice.

I checked and the biome is cold, not freezing, but it is cold enough for the stream to be frozen, yet there is an ant mound on it. The picture also shows two ant mounds directly in limestone.

creature_insects.txt shows that [CREATURE:ANT] has the tag [VERMIN_SOIL_COLONY] - I am assuming that means the mounds should only be placed in soil & not just the ants themselves. It appears the tag [BIOME:NOT_FREEZING] actually checks out.
1) Embark on a site/biome with temperatures cold enough to freeze the local waters or in an area with exposed stone layers (not soil).
2) Observe placement of ant mounds.

This is an incredibly old bug.

Can confirm that this still happens in 40.03.
