About that crash, seems it was completely random, I didn't experienced it for now, also about Serrano, as said Khornaar, drones die quickly in focus formation, even if I don't kite back, when I played it in simulation against Dominators, Kingston drones lives much better because of shield, maybe good idea add to Serrano drones tiny fighter sized shield too?
Also I found funny behavior with Combat Chatter and Automatic Orders mods, these mods treated deployed drones as ships, not as fighters, with Combat Chatter drones at low HP or death says things like "Tell my wife and kids I love them." or other human-like phrases, and with Automatic Orders once drone get damaged below 50% it says damage threshold reached below 50 and retreating, but drone actually work as intended.
