Server spams unrelated messages

[kimden]

During one of races, players encountered Direction is chosen ingame message out of nowhere, repeated many times for some time. The message is supposed to be shown when the direction is fixed or unfixed by a hammer or via vote, but there were no votes (according to the players) and no hammers present in the lobby.

Screenshot:

The server was up for 1 day 19 hours.

It is said that this has already happened before, but somehow went unnoticed.

Steps to reproduce

Unknown for now.

Configuration

STK release version: command-manager-prototype, 8048f98

After this moment the game hasn't ended, but a player has connected (might be unrelated) and the spam stopped.
