Does not crash on startup, it simply removes the item, which is still necessary for crafting recipes. Also, we don't have a fuel cell in our game unless you're talking about uranium fuel cells or antimatter fuel cells.
Just checked, can't find any recipe that uses the DT fuel cell as an ingredient and there are D-He3 and He3-He3 plasma cells that can be used instead of DT. What other mods do you have and what are your RFP mod settings?
I also tried to console in your "rfp-reactor-equipment=Portable aneutronic fusion reactor" from your locale instead to try to use that equipment instead but the console spits back an 'unknown item name' error
Got the same result as you Romner. I guess something in SE is messing with it. I don't know what though since SE doesn't have those extra equipment reactors, just K2 as far as I am aware.
I decided to just console in DT-fuel cells from K2 on our modpack and that works at least as a workaround.
Alright, gonna look into it. Should be fixed at the same time I release RFP+SE integration patch. Will probably take some time though, because I don't have much time/motivation to work on the mod right now (other than bugfixes).
