Any time the stored circuits goes over 128 it flips to -127, maybe you should add a limit?

Edit : Calculator v 1.10-3.1.2
Sonarcore v 1.9.4-3.1.6

Well someone on the modpack dev server just had this issue happened to him. I found out that the right amount of items are in there as The One Probe confirms and you can pipe the items out, it's just a display bug where 128 overflows to -127.

Try updating when I release a new version, as I can't recreate this anymore.
