EDIT: Noticed this issue in 0.0.56, it may have been present before this.

In order to label my Pattern Providers, I made Inscriber Name Presses reading "Assembler" and "Block 1". Placed the former in the top and latter in the bottom of an inscriber. Put in my Pattern Providers. They were correctly named "Assembler Block 1", however, I also ended up with eight of them for every one I put in. This is consistent on my server, happens with other name presses as well, but does NOT happen on other objects I tried (a white sleeping bag from Comforts and a purple concrete block)

CORRECTION: It happens with any block that you put in multiples of, such that if I put in, for instance, seventeen cobblestone, the Inscriber will finish one cycle, the seventeen cobblestone in the input will be reduced to sixteen, and the output will have seventeen cobblestone named as the name presses dictate.

FURTHER CORRECTION: It seems that every time the Inscriber finishes working, it will produce the amount of items that were initially put in, and even if you keep adding more to the stack being processed, the output of each cycle is the same number as was in the stack originally.
