Can you tell me more details about how you deconstructed the emitter? Eg. were there many deconstructions occurring at the same time (of plates and/or emitters)? Were there other mods involved in the deconstruction (of the emitter, or of tiles before the emitter was removed)?

it was first placed emitter and after pushing walls futher and making floor with beton (and replacing stormwall), I deconstructed the emitter and bug occured (Emitter don't have range on other Stormwall but have range on others Emitters). Other Emitters work without problem only the first one I can't deconstruct and I can't even destroy it

Also it was built before update

The emitter was still connected to a tile that no longer exists; 1.4.16 should prevent that from happening, and allow you to deconstruct the bugged emitter without crashing.

yep it's working
thanks for help and really quick fix

now pre-patch wall has the same problem and wall stay even after emitter is deconstracted and some wall don't charge upon placing emitter
but can be replaced with help of bots without crush

sometimes using bots still crush game and on damaging

Did 1.4.17 fix your problems?
