My game crashs when I try to disable the LTN using my shortcut (CTRL + SHIFT + T) to enable/disable LTN.
LTN works fine if I uninstall this mod (autobuild)!
This shortcut is only assigned to LTN! WHithout LTN, this shortcut don't do anything!

Yeah, seems that the eventhandler on_runtime_mod_setting_changed is called with event.player_index = nil
Don't know why, but it's probably safest to fix that case, because according to API documentation it can happen.
Will see to a push a fix soon.

Hopefully, this is fixed now.
