Searching the forum, found this bug as resolved 118055

Current situation: patrolling enemies doesn't move unless a spidertron comes near. Rarely one or two of them move freely among others frozen, feels creepy. Like in the matrix. Didn't even noticed at first because attacks happen normally. Until next happened:
Also just encountered situation, when I just randomly found some hatched biters just standing on my base frozen. No chewing , nothing. Just a chunk of base peppered with statues. Panicked, send a spider to deal, maybe should have leave them be.
Frozen patrolling groups may be not a bug but optimization, though it breaks immersion, but frozen hatchlings clearly are.

Post a save that shows the issue please, see 3638.

Thought I could avoid it, didn't want to share all my blueprints with public. Had to delete them first.
Hatchlings froze on Nauvis base.
Enemies patrolling frozen everywhere.
