Describe the Issue

I have a Cobblemon server up for me and my friends, with some other quality of life mods. The server works just fine, and Waystones function properly. As we played, one by one, different players started to crash when trying to name their Waystone locations. This does not seem to happen in single player worlds, as I have duped the world, tried it in single player and it seemed to allow me to name the Waystone. The Waystones still function, and we can teleport around just fine. It's just that we lose track/end up with a handful of Waystones, which is confusing. I am curious if there are popular mods/known conflicts that could cause this issue.

Your server and client are running different versions of Waystones. Ensure they are the same on both.
