Frozen drones in Escape

I’ve noticed recently in Escape drones frozen with the Cryo gun are meleeing. Maybe this was there all along and I’m just noticing it.

The whole point of freezing them is so they can’t move. Is anyone else experiencing this?

I thought they always thawed unless you killed them ?

True. but it take a few seconds to thaw. It seems like they’re ignoring the freezing effect and meleeing.
