i read it the same way you did. I'm guessing it's something to do with the TiCo/TE3 interaction that makes it broken. I switched back to ducts and if that fails, I'll make an unbreakable one.
The fuzzy works by matching based on the value of the one within, so if you put a full one in with 50% tolerance, it will match anything from full down to 50%, but it won't match further than that, because it's not within 50% range of the one set in the filterso i just tested this stuff, and came to conclusion that you need to put an uncharged pick into import bus filter and set it to 99% or lower, and when weapon gets lower than 99%(or what other number you set) it will be pulled.
