Error when placing emitter:

1128.573 Error MainLoop.cpp:1207: Exception at tick 11373473: The mod Stormwalls (1.3.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Stormwalls::on_built_entity (ID 6)

stack traceback:

Stormwalls/control.lua:376: in function <Stormwalls/control.lua:359>

It seems to happen when trying to place an emitter in range of already build plates/walls.

error when trying to remove emitter:

Same thing, only happens when trying to remove emitter that is in range of plates/walls.

I sometimes get this error when trying to mine an emitter also.

Have exactly the same problems and it drives me nuts

Sorry for the delay on this one, I'm having trouble replicating the issue. Can you tell me any more about the circumstances it happens in?
