I created a new empty world with just that mod and tested the "Guided Missile Targeter Turret", it fires a missile that explodes on impact, so my mod has nothing to do with it.

EDIT: Ah, it only marks the grid if you shoot it while you're controlling it, this is why details are important, because I don't know how you're using it. Let me re-test that with my mod.

Yeah it does affect it, probably because of the game handling different gamelogic hooks improperly... the issue is fixable in their mod though, I'll post something on their mod of what they can do about it.

ok Thanks
