The manual flag recovery option of the CtF mode currently is currently glitched in a certain case:
If a player picks up the enemy flag, and then picks up his own team's flag(from it being dropped), his team's flag will seem to disappear (the enemy flag will remain mounted to the player). The chat message stating that the player picked up his team's flag will still display.
If the player then goes to his flag capture brick, his team's flag will be recovered. The enemy flag is not recovered however, instead it completely disappears, and it's spawn brick must be replanted to "respawn" the flag.
(I've been meaning to report this for months, but I haven't found the time/remembered till now. :S)
