This funny business with ‘aligned’ PP ships going trigger happy was reported at least in 2.1 Beta 4 so is a known issue
There’s also a known issue with NPCs being able to spam rail and plasma guns with no reload time (which I think snuck in during Beta 6 or between Beta 6 and release)
For the record, I’m still Patreus aligned because I’ve been too lazy to sign off (it means going to the pus-play screens in-game), but I’m at basic level (0?) – I have been lucky in that during all of beta and in 2.1 release, the interdictions from other powers has been “normal” … so far
Oi! That's Baron von Schnellenstein to you, mate. No, it doesn't matter that I'm an Imperial Prince!
