Hello! Every time when I go to Nether and come back, all fuel (LEU, TBU, etc) will be duped by pipes to a chest, used normally for depleted fuel. Now I have full inventory of nuclear fuel!

@Gusev-Roman Which version of NC is this? Does this happen with other items or only NC's fuel?

Yes, version 2.18l-1.12.2
Only fission fuels (not depleted) are dupped. Screenshots added.

Now checked on latest version (2.18o) too:
Screenshot 1: before nether -

Screenshot 2: after nether - we can see 29 of TBU fuel appears!

I think, reactor may NOT give away items from input slot :)

Are you saying that the TBU is being pulled from the input slot of the controller?

Yes, fuels are copied, and chunk loading/unloading give us that strange effect.

@Gusev-Roman Would you be able to see if this build fixes the issue?

I will check it today evening

oops! chunks crashed while going to overworld!

Well, believe it or not, that is at leat a sign that a solution is on the right track :P

I'll get another build ready shortly!

@Gusev-Roman Ok, attempt number two!

Crash is gone, but fuels are dupped again :(

@Gusev-Roman Hmm... are you sure? I'm not saving the controller's inventory to the port any more, so is it definitely not just pulling from the controller's inventory?

Dupe is fixed in 2.18q! Thanks!
