Before 1.19.80, the old world loaded did look fine. But after 1.19.80 update, the old world from version 0.9.0 until 0.11.1 loaded will have lots of errors.

Steps to reproduce:

1. Import and open the attached worlds: MCPE-174300 C.mcworld, MCPE-173400 S.mcworld
2. Walk around and try to break/place blocks

Observed result:
You will walk too fast. Even if you die and respawn, that speed effect never stops. You will not be able to hit, break, and use anything that is near you.

Expected result:
You walk at normal speed. You are able to do everything a person with Member status can.

Notes:
It can only be reproduced in version 1.19.80 up to the current version.
