If you put a turret on a space ship (which you have to otherwise you get killed by space debris), then remove the turret, it leaves behind a hidden turret shield which renders the space unbuildable as a result. There did seem to be a trigger where it did a cleanup of shields with missing turrets, but it only seems to do this on a mod change. There should be a way to trigger this analysis and do the cleanup (this problem also occurs with the OwnlyMe version of the mod)

Otherwise, I love this mod

When running this mod with space exploration mod, I get this error:

Error while running event KingsTurret-Shields::on_tick (ID 0)
KingsTurret-Shields/on_tick.lua:11: attempt to index field '?' (a nil value)
stack traceback:
KingsTurret-Shields/on_tick.lua:11: in function <KingsTurret-Shields/on_tick.lua:4>

I have the same issue, but I don't have space exploration ;
In my case I wonder if the mod colliding could be "endgame combat", because everything was working as intended befor that addition.

Love the mod too.
