ok, we got it to work, but only after uninstalling and reinstalling the mod, idfk any more, but at least this somehow fixes it

Aye, that is an oversight of ITA (I've reported it but lord knows when they will fix it).

This mod is purely for making Incendium Fuel Rods work with ITA.

If the devs take too long, I might tinker with the Volatile Fulgurium Rod.

This mod seems not to fix the existing issue of EK always overwriting ITA's Volatile Fulgurium rod, the tool tip says it is modifying it but the problem still persists that they stack, can be in hotbar, and do not produce burn the area around them or give nuclear waste exposure

Please note that I changed the load order, this patch comes AFTER both ITA and EK.

Putting it in between the two for some reasons triggers EK's Volatile Fulgurium Rods to overwrite ITA's (meaning you won't have to cool them down).

Don't ask me how that works since my mod should touch nothing of but...here we are.
Just switch load order and restart and it should work as intended. :)
