[4.0]Building on the tiny square near creeps entrance

[Guest knowell]

Near the creeps entrance there is a small 2x2 square. The Red player can't build anything on it. Brown player can build 3 towers in it. Yellow can build 4 towers in it. I believe this is a bug maybe. I wouldn't at all about this in the public since it is a bad position but in the survivor 4.0 endgame, we abuse the game by building on every single buildable piece of land. And four level 3 magic towers (wizardry?) can be of use here.

Please refer to screenshots.

Already fixed for the soon to be released 4.1. Thank you for reporting though.
