I tried to shift click to make a stone sword and it worked, however to make an Iron furnace from IC², when I shift click, the screen goes back to the crafting table and nothing happens.

I will also leave a list of the mods I am using in case its useful. (Its easier for me to just crash the game to get it though)

Weird, it worked fine with the Generator's recipe..
(And now it doesnt work with anything again, I dont get it..)

I cannot reproduce in dev env, so one of your mods installed should be involved in this issue.

Same issue, did you manage to fix it?
