Is it possible to add a line to the custom turret setting to allow for slot size change? I have changed the size of these chainguns and re-spawned a stack dozens of times but can't get it to take 2 slots (ideally on a size 2 turret) and will always take 3, even with a 0.5 gun, this also appeared the case when faffing with damage and stuff but I didnt check that, I was too busy aiming for a 10km range 150dmg(per shot) chaingun and didnt spot my slot problem til after.
*Further update* After cutting losses, and realising that the station i could buy back the single barreled ones I spawned from was... well... in my way during a pirate attack... I had to spawn another set, 4 sets in I get another single barreled set, but this time I notice that 2 of the 4 sets have 2 slot use, not 3, so not sure if that helps, but I still have no idea why none of the others I done earlier came out that way...
