Happened twice now - upon the timer running out for level 15 to level 16 - with all requirements filled (or clicking the next level button) the game crashes and I'm hit with this error message. Happened twice on different play through, only happened since 0.13
Cheers,Error while running the event handler: ...Data/Roaming/Factorio/temp/currently-playing/control.lua:346: attempt to index field '?' (a nil value)
