Added the lite planet pack modpack, (minus the dea dia system because it was alpha) and enemy race manager and somehow the damage bug for the advanced laser cannon came back. (laser damage) and the electric damage for the electron beam (electric damage)
This only happened to the laser and electric damage on your turrets and no other turrets. The damage on the gatling turret doesn't seem to be affected so seems to only be these two.
Somehow King Jo's entity master is in the list and that mod have been updated recently so i don't know if that mod affect yours somehow. But my best bet is the Castra planet mod messing with some stat, will try and disable it and test, will come back with the result.
