The problem I am seeing is that whenever an explosion or EMP occurs at a particular location on the map, a block of characters (including the alphabet) appears at that location. The size of the block is proportional to the size of the explosion that occurred.
The image at the link below shows the moment that this problem started. A large number of ticks were exploding in the same place at the same time. The effect occurred and it has been occurring ever since.
Unfortunately I haven't documented very well, so I can't remember if the image that appears subsequently fades over time. Later I will check to see if I can see the effect in a replay.
Also, I copied the following text from the ZeroKLobbyErrors files after the problem occurred:
