No, it wasn't posted...
This bug also happens with Flag locks. It won't reset the timer and you have to wait until the first lock ends (COMPLETELY).
It's about how flag locks works. You have to wait untill 1st lock is gone before using 2nd on SAME flag. If you use 2 flag locks on same flag, time isn't added / timer don't reset (that's NOT a bug imo).
So:
1) you lock a flag
2) wait 40 second and lock it again (while it was locked 5s more by old lock)
3) after 5s lock dissapear (game don't count 2nd lock at all)
But if flags timer would reset everytime you lock flag again... You could just tp anytime to locked flag, and lock it again and again and again.
Right now, you can't tp too fast to flag locked by your team when 2 opponents are right there. You have to wait untill 1st lock is gone to lock flag again. So opponents have time to recapture flag (it's possible to them). And imo that's how it should work.
BTW: Yeah, Circle of Fire bug exists and need to be fixed (but knowing GPG this won't happen in near future
).
