1. A sharp decrease in FPS when loading the world/connecting to the server/when opening the settings menu. Also, during the game in the world and on servers, FPS can drop sharply from 60-50 to 25-15 (and begins to sag)

2. Slightly blunts the game loading window (because of this, it goes too long)

3. Sometimes it is impossible to log in to XBOX. Sometimes it throws out after logging in to the main menu, and nothing is included.

4. The skin can often reset to the standard one. There can also be an infinite loading of the skin model in the main menu.

5. After it failed to connect to some network world — it will not be able to connect to the single-user world, it will write that " The connection is broken due to the unavailability of the world"

Suggestions:
1. Make sure that the @s in the command blocks and NPC points to the player, and not to the object with which the command is called.
