Hey there, I was just playing an game with some orbital battles going on. The enemy had defeated my forces, and were trying finish off my orbital factories. I had a death laser on infinite build in a factory, and when the avengers would kill it, it would instantly try to build another one. This would cause them to destroy the death lasers built about 7-8 times a second in the one factory. It was a huge on screen spam along with some audio spam. Hope this helps! Thanks!
Yeah this happens sometimes with air units as well. When an air unit is about to finish it gets shot down instead and then keeps getting shot down forever. Not sure how this one would be fixed, it's more of a native problem with projectiles than anything.
