I am running BEX CE 1.8.1.4 (which includes the Performance fix) and I have also noted this behavior from time to time. It seems weirdly intermittent, but definitely some enemy mechs just seem to attack less than they should. I actually wonder if it might be a feature, rather than a bug, as I seem to notice it more in CQB situations where mechs who take a pasting, will sometimes back away and not return fire or only fire one laser. Almost like the pilot got rattled, panicked a bit, and just bugged the hell out. Weird, but not unrealistic behavior. And it does make the game easier, which I don't think is a benefit. Anyway, can anyone shed any light on whether this is a cool feature or a weird bug, and if the latter, any solutions? Thanks
