I'd love to do some map making, but I'm already trying to make an IT server. I could give ideas though, and maybe when I can't work on the server or don't need to do anything, I could do some map making?
I just really wish some things from old FH were in the new one, like South Pole. All the maps feel similar, which is a bit annoying, but the maps are done very well! Only a bit of lag issues and that's mostly on a busy day or old laptop, and usually turning the camera away from a crowed or object filled spot helps.
Good luck with future updates!
