We are experiencing a (likely game-sided) bug in the latest Minecraft update, which prevents us from switching skins during gameplay. This affects switching costumes and certain games such as DeathRun and Hide and Seek. This only affects your own player skin - you can see other players including NPCs with no issues.

For those updated to the new version, we suggest you leave and rejoin the server after selecting a costume.

As this is a not a major game update, and your platform allows you to, you can avoid installing the update until this issue is resolved. We will release a new update post once this is resolved.
