I was able to get a server running without issue. And when I run my update script: start "" steamcmd.exe +login user pw +force_install_dir "D:\Steam\steamapps\common\PixARK" +app_update 593600 validate +quit It runs, and it validates. Then it completes saying "Success! App '593600' fully installed." It never allocates space, it never downloads. However I know there is an update because it says it is running version 1.5 and 1.7 is the current version. And when I try to connect, the client says that there is a version mismatch (so I cannot connect).
