Custom avatar scalers like the Jackal Scaling System or Mags Scale Adjuster have been broken by the latest beta update. Before the update you could use these to select a custom size multiplier and then reload your avatar to be set to that scale. Usually this would be done by toggling OSC off and on, but just switching out and back into the avatar would usually also work. I have provided a public avatar with the Jackal Scaling System for testing.
Steps to reproduce:
  1. Use avatar with custom scaler.
  2. Select any custom size (for example 5x)
  3. Reload avatar (either toggle OSC off and back on, or switch away and back to the avatar)
  4. Notice how in the beta your eye height did not change but your body has. Whereas on live the scaler is working fully as intended.
This seems to be caused by a change in how the TPose animator is loaded or handled in the latest beta update.
