I crash when trying to export on newer versions of Factory Planner. Specifically, Factory Planner 2.0.47 changed power and emissions to be products/ingredients instead of their own separate things. Now, trying to export shows an error in magic-huts:::on_gui_click:

magic-huts/scripts/factoryplanner.lue:274: attempt to index field '?' (a nil value)

Rolling back to Factory Planner 2.0.46 works fine.

yeah factory planner made changes to their mod that i cannot work around nicely, downgrading to .46 is indeed the fix for now.
