Yesterday all of these, except Special Item, were updated to their 1.4.4.9 versions.
Unexpectedly they have introduced the following issues which will be fixed today:
Gamemodes now has two commands starting with j so you can’t currently use /j
Gamemode flags not applying to lobbies
Gamemodes crashing clients (need confirmation)
And Special Item will be updated.
If you type /who you should see which entrypoint you are connected to.
The next update will be for Build to be updated to 1.4.4.9 which should happen over the next week unless other issues show up. Build will be updated but with the caveat that new items used in builds are not protected properly as part of our ability to rollback grief.
