There is an issue with VMH - Variable Mob Height

Make a test with deleting its config first - if there is no change, remove this mod

im not seeing that mod in neither the config or in the mod list.

The file name is vmh-1.2.2-1.18.2.jar

there is no mod of by that name in my server configs or the modlist.

Add the full crash-report
