Server Version

This server is running Paper version 1.21.1-74-master@971a7a5 (2024-09-08T20:24:20Z) (Implementing API version 1.21.1-R0.1-SNAPSHOT)
Console
You are running the latest version
Previous version: 1.21.1-26-52ae4ad (MC: 1.21.1)

Bug Description

keepSpawnInMemory is not retaining the false state, have attempted to trash the old file and let it auto populate a new file, tried adjusting with the server both down and up with stops/restarts. Problem didn't seem to be present with previous versions pre 1.20 just started to noticed upon update to 1.21 + content.

Steps to reproduce

Shut down server
set keepSpawnInMemory: 'false'
start server
go back into worlds.yml and note the change didn't persist.

if you repeat these steps and instead set
set keepSpawnInMemory: false (with out the 'false')
console will spit out
[Multiverse-Core]: Exception while loading value for keepSpawnInMemory
I know this isn't the way was just attempting various things at this point to get it to take.

Agreements

• I have searched for and ensured there isn't already an open or resolved issue(s) regarding this.
• I was able to reproduce my issue on a freshly setup and up-to-date server with the latest version of Multiverse plugins with no other plugins and with no kinds of other server or client mods.

I can confirm this. the memory property is not saved.

Even though a lag report shows no loaded chunks etc on restart it reverts back to being loaded

i'm having the same issue 😭
