Error while running event mushroom-cloud::on_tick (ID 0)
LuaRenderObject API call when LuaRenderObject was invalid.
stack traceback:
[C]: in function 'newindex'
__mushroom-cloud/control.lua:136: in function <mushroom-cloud/control.lua:103>
I triggered the explosion while in the map editor. Heated the reactor up and sent an asteroid, for fun. Might well happen in normal game, too.
