For the last few month I was quite out of time, so my AUR pkg pokemon-revolution-online was out-of-date all the time.
Thanks to the user BlondVador I got a little notifications that pointed me to that problem and today there is some time left for this. So finally I was able to switch the data part to my gitlab-repo and leave only the pkgbuild at the AUR.
Not a big change, but something I wanted to do for a while.
So thanks for all the help and I hope you enjoy the game.
