I don't know if it's been previously mentioned...and I don't know if it is the way that valve does it on tc_hydro...but we were playing this on my server the other day and blu pushed red all the way back to the last point, and then red won and pushed blu all the way back to the village. I'm guessing time ran out or something, as the map ended.
I noticed that both teams had 0 points when the scoreboard screen came up. It kind of felt like each team should have had 1 point for every round they won.
Also, there was this point on the boat where I expected to see a respawn room visualizer or the little hand telling me I couldn't go through this door.
There's no way of knowing if that was intentional or neglect...but I thought you should know that as a player the way it is now I thought it was going to open when I ran up to it.
