When using Blueprint Sandboxes there is a rare chance picking up the cube will cause the following error:
Error while running event Ultracube::on_tick (ID 0)
'entity': table expected, got nil
stack traceback:
[C]: in function 'add_custom_alert'
Ultracube/scripts/cube_fx.lua:95: in function 'cube_alert'
Ultracube/scripts/cube_fx.lua:587: in function 'tick'
Ultracube/control.lua:317: in function <Ultracube/control.lua:315>

Most of the time it works fine but sometimes for unknown reasons it just doesnt.

oh, also im linking here to 3 save files from my auto saves since i dont know which one would be the most useful.
