Details

I was able to reproduce my issue on a freshly setup and up-to-date server with the latest version of Multiverse plugins.

Description
Regenerating an AMPLIFIED world regenerates as NORMAL

Steps to reproduce
create a new amplified world

regenerate that world (seed settings do not matter)

that world is now a normal world

in addition amplified worlds are not tagged as type AMPLIFIED in the world config file

Expected behavior

regenerating an AMPLIFIED world does not change the world type

I manage to reproduce the issue. But it looks like a server bug. Some custom logging for reference:

> mv create test2 normal -t AMPLIFIED

Same problem with FLAT worlds

Having the same issue now on 1.21. flat worlds only generate normal worlds w/ the datapack gen i have. Cleanroom generator seems to be the only workaround currently.
