Describe the bug
When I come back to my server, my flying machine from VieCraft Machines mod (https://www.curseforge.com/minecraft/mc-mods/viescraft-airships) that was here before I log out has just disappear.
I use this mod for a long time and never have had this issue.
It happends twice in a week since I have added Performance tweaks mods to my mod pack (https://www.curseforge.com/minecraft/modpacks/raoultech)

maybe the cleaner clean too much ? :)

To Reproduce
Steps to reproduce the behavior:

1. Craft a VieCraft machine
2. Play
3. Log out / Log in
4. randomly see the issue

Thanks for the report. The issue is fixed with today's update.

I was not able to reproduce the issue locally but was able to reproduce the issue on my dedicated multiplayer server after spawning 65 viescraft machines.

Anyways I added some additional compatibility with other mods with this update, so please let me know if you run into any other issues. Thanks.

Wahoo, thank you for all theses tests
I will tell you if the bug occurs again
