[1.7.10...yes I know it's a fossil]mod compat problem

[Twisted-Code]

Describe the bug
I will honestly be surprised if this gets fixed short of a pull request, and even slightly surprised if this gets a response (the fact I'm even playing on 1.7.10 when I know it's basically a fossil is only due to nostalgia), but nonetheless I at least wanted to document that there's a small issue with this mod's foci not showing up sometimes. I don't know whether it's on this side of the fence, Thaumcraft's, or Forbidden Magic', but when both the wrench focus and Forbidden Magic's blink focus are in my pouch or inventory (as opposed to equipped), only one will show up on the selection wheel. If one of them is equipped on a wand (or staff), the other will show up. Either focus can end up being hidden, with no rhyme or reason other than possibly search order?
Steps to Reproduce
Steps to reproduce the behavior:

1. Have a ton of mods like I do (maybe not strictly necessary? But I have no idea)
2. Craft your wrench focus and Forbidden Magic's blink focus (or possibly one of the others)
3. Have those two foci in your inventory
4. hold your focus switching key. The wheel will show up as usual, but only list one focus

Expected behavior
I expected to see both foci, as opposed to just one of the 2

same thing in my test world so it's not just the server
