I crafted one of these for my expert playthrough of Infinity Beyond, and it's been giving me fits. Sometimes it'll work exactly as I'd expect, and it does its job well. But for the past five minutes (and occasionally in the past), it's just been making noises and not actually exchanging anything. Just a minute ago, I tried swapping a different block, and it worked once. Then it stopped working again and hasn't worked since. Are there any known bugs with this mod? Did some googling and didn't find anything, and the wiki page on it didn't mention anything either. This is quite frustrating.
