Model loss after switching worlds ，Version 4.0.6 and below

Try only using essential plugins to reproduce this issue. If it happens. please provide steps and your server setup such as server fork, version, and plugins.

Unfortunately, it still happened, and there is something even more strange - this phenomenon can occur in different parts of the same world, which makes me very confused

Server version: 1.19.4 Paper

The triggering steps are: use the command "/warp 卡露蒂亚" to generate a monster in the world named kldy, use the CMI command "/spawn" to return to another world, and use "/back" to return to the kldy world. The monster's model will disappear

Can I upload my server to you somewhere

This symptom also appears in the same world Summon the model far away from the spawnpoint, enter spawn, and then execute the back command.

wow, the model is gone

This confuses me because MEG3 does not have this problem

I need to solve this problem because it has always existed
