Hey.
5dims resource, replace fast_replaceable_group of electric-furnace building to "electric-furnace" (from "furnace")
This cause exception on game start.
Now, IIRC this could be dynamically detected (see if 5dims is enabled) and use different value.
PS - i know 5dims mod is to blame here, but on first thought (looking that exception is coming from electic-furnace) i decided to post here.
