When using a bed or a respawn anchor, there is noticeable lag. This happens when the player sleeps in the bed or sets the spawn point.

This seems to happen mostly when a bed or respawn anchor is used for the first time after loading the world. After the first use, subsequent uses appear normal. It is difficult to reproduce in a newly-created world.

The issue is most likely to occur when a player uses a bed or respawn anchor for the first time when sleeping is not possible. A clear lag spike occurs before the game displays the message: "You can sleep only at night and during thunderstorms". Sometimes it happens before sleeping in a bed successfully but this is less common. It will only happen once per session.
