When shift+left click is pressed on any entity to paste settings, and no source entity has yet been defined by shift+right click, TFC crashes in some paste hook somewhere:
250.283 Error MainLoop.cpp:1195: Exception at tick 120837515: The mod The Fat Controller caused a non-recoverable error.
Please report this error to the mod author.
Error while running event TheFatController::on_pre_entity_settings_pasted (ID 30)
__TheFatController__/control.lua:839: table index is nil
stack traceback:
__TheFatController__/control.lua:839: in function 'decreaseStationCount'
__TheFatController__/control.lua:858: in function 'on_station_rename'
__TheFatController__/control.lua:867: in function <__TheFatController__/control.lua:865>
I am able to consistently reproduce this by shift + left clicking any entity that supports copy/paste settings immediately upon loading a save file, without shift + right clicking anything first. The error is stated to be "non-recoverable" and the game immediately exits.
