What happened:
By running around the map and destroying bug nests with artillery support, the nests and worms become invulnerable for a while and cannot be targeted.

Ways to reproduce the bug:
Turn on the remote artillery control and right-click several times on the cluster of worms and bitter nests. That's it, during the flight of artillery shells, nests and worms become invulnerable, you can't aim at them and shoot with the space bar, and the defender/destroer drones will ignore them. Most likely, this is because the game already considers them dead, but nevertheless they spit back and spawn new biters, while they remain invulnerable and untargetable.

Thanks for the report. This is working as intended. If you want the artillery to kill them, then let it, otherwise you can simply *not* shoot them with artillery if you plan on killing them manually.

Thank you
