Real cool what you've done with this new race and the new functions you've added; one issue i'm having is the audio. When masklings attack my center, the plasma-arrows will keep give off this ear piercing thump that somehow gets progressively louder if you have the game paused while the attack is going on, before sputtering out like a dying car engine. Oddly enough, while redoing that i noticed if i try to unpause the game while it's in it's sputtering stage the game will refuse to unpause(even if i move the camera away from the source). I've experienced the same issue in older game versions when i put the speed to x3, so the cause of those issues may be similar.
I think I found the problem. The ranged attack animation and the factory animation are fighting, as a result the structure thinks it's always starting a ranged attack, and so launches an arrow. I'm not sure if there's a way to fix that with the mod, outside of removing the transformation or removing the ranged attack.
The animation logic is different in 2.2, so it shouldn't be a problem then.
