PopeyeOnGamepad If you aren't in the Discord server I can see why you weren't aware of the COUNTLESS statements to server owners to prepare for the update needing changes on their end to remain compatible.
We even gave out a build 4 days in advance for server owners to update their setup before it would update globally.
There was a lot of code debt that had been building up over the years, and we decided to refactor the client for a better base to work on in the future. This also fixed innumerable long standing bugs.
If you don't want to spend the time to update to be compatible with a far more improved version of the client; that's up to you.
