When trying to deconstruct a combinator with an on_tick event:
Error while running event LuaCombinator3::on_tick (ID 0)
__LuaCombinator3__/control.lua:239: table index is nil
stack traceback:
__LuaCombinator3__/control.lua:239: in function 'destroy_combinator983'
__LuaCombinator3__/control.lua:1098: in function <__LuaCombinator3__/control.lua:1071>
Changing id to unit_nr983 at control.lua:239 resolves the problem.
