Kinda tough to explain, but hopefully this should clear it up a bit:
(The command combined with /static in the image is /copy.)
/ignore lots of people to get a good shot.
/static (on)
/copy
Punch two blocks
(/bi activates automatically)
Punch one more
Commands that this happens with: /copy, /zadd, (probably more, but I've no idea which ones)
Kind of a confusing effect...
Thanks for looking into it!
EDIT: It seems like it's remembering the last command I succesfully used /static with, which was /bi, even though I turned static off and back on. When I restarted WoM, I had a blank /static slate, and it didn't activate /bi on its own, it simply did nothing.
