I believe that the broken commands is
/my tp, which accepts either on or off.
Please allow me to explain why this is broken. I've been working on rewriting the entire account system and database system over the past few months. As part of this, we're moving to a new database structure for storing all of a player's information. The current structure has 78 columns to store information, which is completely excessive and many of these settings aren't being used. The new structure has 43 columns, in which a lot of settings have been combined when they have a similar purpose. Furthermore, we've removed almost 20 features from the gamemode as part of cleanups. Unfortunately, disabling teleportation is part of this.
As you may know, we're working on
re-thinking the teleportation system altogether. The current system is very badly designed and has a lot of issues. For example, disabling other players from teleporting to you is something that ideally should be persistent. Cleaning up this code makes it a lot easier to move to the new account system, which we'll do within a few weeks.
Unfortunately, looking forward, in the short term a few more features are likely to break. Most importantly, the gang system is likely to loose a significant part of its functionality as it has to be rewritten as well. We're hoping to vastly improve communication about this, which we're doing by involving all of you in these decisions.
tl;dr: We're aware that it's broken. Sorry. More features may break in the next few weeks, but we'll bring them back very shortly afterwards without bugs and with much improved usability.
