It's in the cjass chain template thread, when I was trying to improve group usage by putting the FirstOfGroup in the filter. But the thread got hijacked for a different discussion, so I'm asking here :D
I'm glad to hear that. I'll make a mental note to investigate some time.
Sounds like a system fault, obviously. If I can trace it back and you're right, I'll fix & credit. Low priority on the to-do list, though.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
