I had reported this issue to ProjectE and someone said it might be because of the sorting feature you guys have. Every time click sort button on the transmutation table it brings up the previous item I wanted to duplicate for EMC on the left side. Then I can just take it from the left side for free and use it to burn for more EMC thus infinite EMC.

here is my current logs if you need it: https://pastebin.com/R4iyAWGH

Hello! Quark's moved to 1.18 now-- unfortunately, this means that (unless your bug is critical and/or game-breaking), we're closing support for issues filed for versions prior to it (e.g. Quark on 1.16).

If your issue still occurs on 1.18, or if your issue happens to be rather critical (e.g. consistently crashing the game with no other mods present), please leave another note or open a new issue. Thanks for your cooperation!
