Couple of things:

(I have not tested in a blank world with no other mods)

1. Gimbaled laser turrets (light/heavy) seem to stop generating their own ammo after a few dakka, seems to be rectified for a couple more dakka if you take manual control. When you release control, the AI will get a couple more dakka before failing to dakka again. This issue could potentially be caused by another mod. (looking at you, nanites)

2. Anti-fighter turrets are often failing to hit small grid targets, owing to the space between the dual beams, the small grid block (mostly gyros I have noticed) sits in between the two beams and the laser never hit the target. The laser will continue to dakka until the block is manually removed, usually resulting in several fried engineers.

3. Anti-fighter turrets again; when aiming, these turrets do not seem to take into account their dual beams, instead aiming from the center of the turret, this is a problem when avoiding destroying their own grids as when the dakka comes out, a beam will usually clip another turret or block on the same grid.
