What happened?

Issue is in the title; server log includes:

Steps to reproduce

1.install HungerGames v5.1.1 on PaperMC 26.2-112
2.create arena as per the wiki
3.join arena -- reported issues occur
4./hg debug test_arena reports that the arena is ready to run

Expected behavior

arena timer to commence countdown, world border to spawn? and shrink (theoretically), players to be able to combat with eachother and not be immortal to other environmental damage.

HungerGames Version

5.1.1

Server Version

Paper 26.2-112

Additional Information

[bootstrap] Running Java 26 (OpenJDK 64-Bit Server VM 26.0.2; Arch Linux null) on Linux 7.1.8-1-cachyos (amd64)
It may be notable that I am using the "arena-center" border center option -- I will test with others and report back here.
Thanks for any help
