I built my Power Armor MK3 and Portable Fusion Reactor MK2. After placing the new fusion reactor, an issue came up asking for fuel source. When I tried placing coal, I get a message pop up "Unknown key:"Fuel-Catagory-name only. Undal-compressed-Fusion" fuel. I have tried other fuel sources and get the same message.

Can anybody help????

Mod list/log please. This is a mod error, so you should try to find out which mod is the issue and report it there.

Base game doesn't have power armor mk3 nor portable fusion reactor mk2, so it is a problem with some mod you are using. Moving to technical help.
