Someone from the MCBE Realm Hub Discord, a discord server aimed to help in the development of realms and to overall make MCBE realms better, this person figured out that GameTest can be used as custom chat commands, custom chat ranks, and things you could not normally do with normal commands and addons. However eventually a problem was discovered, sometimes GameTests decides to break, and I’m not sure as if this will replicate the problem but usually for me editing the GameTest and saving it while in-game. I have also attached screenshots of the code and the errors. If you want the link to the base addon the link is here: https://github.com/notbeer/MCBE-GameTest-FrameWork

Quick Note:
Sometimes when GameTest breaks it work for some but not others.
