Error while running event RenaiTransportation::on_script_trigger_effect (ID 152)
RenaiTransportation/script/event/effect_triggered.lua:10: attempt to index field 'source_entity' (a nil value)
stack traceback:
RenaiTransportation/script/event/effect_triggered.lua:10: in function <RenaiTransportation/script/event/effect_triggered.lua:8>

I don't know much about the editor mode cause I've never really used it. What kind of things were you doing in it when it crashed?

just pushed "C" key (attack the target) without any current weapon or a stack in hands. Attacked a land mine
