Ok so this is an issue my partner and I have run into recently while trying to update to the latest update for Vintage Story, we're both on linux mint and when we try to use all the different methods of updating including as using install.sh or the flatpak. I've even gone so far as to try and manually remove every last trace of the game from my computer, when I restart, the application is still there and still opens up to the 1.21.5 version, any advice on how to proceed? am I stuck on 1.21.5 forever or is there a way for me to still be able to update my partner and I's games?
