Texture still missing from two of the most popular ships in the game Ides and Mercury.( it is the same basic module space suit dock facing texture)
Pirates still Bugged
Flight pathing still bugged out of PHQ sector
Xenon defense station module still unkillable ( add Xenon shipyard to that now )
Half repaired docks still not being repaired ( so any mission related activity cant complete)
Defense drones blocking all docking pads on 'yard complex
hundreds of unowned ships and minefields littering space.
NPC being able to stand on the outside cockpit of PLAYER ships whilst in space ( need to workout how to screenshot this beauty )
Xenon Warning muisc following player for sectors and sectors and sectors and on and on and on and on and still associated with now unowned unkillable unremovable Build Storage
On a positive note I did like the previous atrocious docking behaviour being blamed on Faulty Smart Chips

Another odd thing was that all but one of NPC Self Defense Station's were removed from other FACTION space which they then went on to start building anew plus a whole stew of food and med stations started being built across all sectors
feel free to add anything I have missed and add any I havent found that have appeared in 2.5
