NC Version: 2.18c
Everytime when I right click a nuclear furnace it would crash.
Crash report: https://pastebin.com/W3qmenCX

@ChlorineX Does the bug persist in version 2.18d? I couldn't recreate the issue in either 2.18c or 2.18d.

@ChlorineX @HydrogenC Does this build fix the issue? I still can't recreate it on my side, strangely.

I succeeded in opening the furnace’s GUI at first, I attempted to smelt Cf-251 Oxide into Cf-251 using Thorium ingots. When I clicked the furnace to check the progress later, it crashed. I tried to click it several more times, and it kept to crash.

Fixed in 2.18e ;)

It does, thanks a lot. Actually, even in 2.18c, the bug is still really rare and very hard to reproduce.
