I've been making up these hex fillers for the building bases. A number of play-testers have mentioned that the original layout was confusing, and I can understand it. LOS through the partial hexes could be confusing, not to mention movement. This will probably spread out the buildings more and quite possibly require that I make 2 more hex tiles. I'm looking forward to seeing how MM plays with these changes.
I'm also working on changing the initiative as it is now and add alternating activation for each player.
