I had a crash:
The mod Shield Generators (0.4.1) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event shield-generators::on_tick (ID 0)
shield-generators/control.lua:623: attempt to get length of field 'tracked_dirty' (a nil value)
stack traceback:
shield-generators/control.lua:623: in function <shield-generators/control.lua:594>
seems to happen when the shield protects the rocket silo and its shield bar fills up.
