No objections per se, and I don't know anything about the mapmaking/foundry process here, but in
Game 13326601, with Trench settings, I was able to attack into and subsequently attack from (which shouldn't be possible when playing Trench) Manayunk, Tacony, and Pennypack in the same turns, respectively.

I know the map is out of Beta mode, but it seems those are some glitches that made it into the code unnoticed. I did a quick search and it doesn't seem like that problem was raised before. Just thought I'd share my findings.
