Game crashes when I try to use Krastorio 2 miners:
Error while running event OutpostPlanner1-1::on_gui_click (ID 1) OutpostPlanner1-1/gui.lua:544: attempt to index global 'state' (a nil value)
stack traceback: OutpostPlanner1-1/gui.lua:544: in function 'miner_button_click' OutpostPlanner1-1/gui.lua:1070: in function <OutpostPlanner1-1/gui.lua:1053>
Should be fixed in 1.2.3. This probably isn't specific to K2.
It happened when switching out miners (of the same size) when the old blueprint also had modules configured.
