I have found what I believe is a significant bug/exploit in Entrenchment that I don't want to post.  How can I deliver it to someone that cares?

Also, I tried to take screen shots of this and didn't get any ingame feedback like we used to from the game indicating a successful screenshot nor can I find any obvious files in any obvious folders?

My keybindings indicate "printscrn" but neither hitting that nor any combination of that and either control or alt seemed to be effective.
