Pretty much title. This is for campaign, but i assume it happens in multiplayer. Very easy to test with Thorgrim's campaign. Get hit by 1-2 archer units with the gyrobomber and it refuses to listen to commands whatsoever. Looks like it gets stuck in animations or something. Seems to be the case for any archer unit but I did not test with other missile units besides skavenslaves. I only tried it with gyrobombers; I have no clue if it affects gyrocopters the same way.
