Bug Description

I have a mining that I regenerate regularly so that the resources are replenished. I also change the seed so that the players can't remember where minerals are. For this purpose I use the command /mv regen mine -s which works fine.
The problem is that as soon as I try teleporting in this world, either I get a "no safe location found" message, or I spawn in the middle of water or other unsafe places.
I gather that this is because the spawnLocation in the worlds.yml config file remains unchanged after a regen.
I tried editing that file to remove spawnLocation but it comes back (although more suited to the new world it appears)
I my mind, regenerating a world with a seed change should also reset the spawnLocation.

Steps to reproduce

• start a server with multiverse
• create a world mv create another NORMAL
• teleport to it mvtp another
• you are safe
• mvtp world
• /mv regen another -s
• /mv confirm
• /mvtp another
• you might get "no safe location found" or arrive in water or arrive on land.

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.
