[0.12.33] biter stuck on building, flickering pathing

[sparr]

In the attached save, if you walk a few dozen tiles east you'll find a biter stuck on a pumpjack. He is flickering at about 60fps, one tick he's on a one-step path to the pumpjack, the next tick he's walking away with no path, then back.

I see absolutely no biter, stuck or otherwise.

Here's what it looks like, slowed down:

That's very nice, but doesn't help me reproduce it at all.

It looks like you're using mods. So please upload your mod folder. I probably won't get that biter without your mods.

Thanks. This will be fixed in 0.13.0.
