World border resetting bug

[funnycubeguy]

Mohist 609 build. If you set the world border reboot then set the world border again to a different size and reboot the world border will reset back to the first border you set it to. The border does not work in other dimensions either. It combines all the dimensions borders to the main world border.

Seems like a long time issue: https://www.minecraftforum.net/forums/support/server-support-and/3065929-worldborders-get-reset-every-time-server-restarts
