The Game crashed when i tried to load my electric VW-Transporter (https://mods.factorio.com/mod/vwtransporter_A16) onto the wagon.

"Error while running event vwtransporter_A16::on_tick (ID 0)
LuaEntity API call when LuaEntity was invalid.
stack traceback:
vwtransporter_A16/electric/lib.lua:148: in function 'fuel_tick'
vwtransporter_A16/electric/lib.lua:212: in function <vwtransporter_A16/electric/lib.lua:211>

"

any way to solve this? thanks!

Looks like the VW Transporter mod does not check if the vehicle is valid when adding fuel to it, and also does not listen for the script_raised_destroy event that will tell when it is loaded and deleted. It will also need to listen for script_raised_built to resume adding fuel when the vehicle is unloaded and created. Please submit this to that mod's author as a bug.

Ok i tested it and it looks fixed thx to your hints.

Fun fact: the cargo van is not allowed to load. Did you blacklist it intentionally?

Cu, steinio.

It was added to the blacklist a long time ago, probably because of the bug that was just fixed. I'll check if it can be removed now.
