0001209: Hyperspeed Rat, other vermin
In my current fortress, there is a rat in one of the carverns who moves insanely fast; about once per every 3 frames, where my dwarves were moving once every 20 frames. It looks really weird seeing a rat move at supersonic speed, but it doesn't impact gameplay much(aside from being distracting) because they don't attack dwarves or anything.
Only seems to have happened with this one rat.

Yeah, this has been happening with other types of vermin too. I thought it was expected behavior when I saw it with bats (it looks awesome), but rats... not so much.

This is odd, at first I chalked it up to FPS improvements, etc.

They do have the same [SPEED] rates since 40d.

Does [BODY_SIZE] affect [SPEED]?

Unsure about body size... Seems unlikely though.

I'm not sure the RAWs have anything to do with it though, because it only happens occasionally. 98% of vermin are normal speed, but that 2% are just too fast... I've had this occurrence about 3 times now.

It's possible that this rat didn't have its caste set properly - currently, attempting to create a vermin using a custom reaction will result in this same behavior.

A save with one of these vermin on screen would be appreciated.
