Describe the Issue

Waystones were working normally. No changes to settings or mods. After logging in today and several times after all waystones have deactivated back to their "undescovered" state even after reactivation of all sites.

Do you use any performance-enhancing mods (e.g. OptiFine)?

Optifine 1.18.1 HD_U_H4

Waystone data is saved as NBT in the waystones.dat file (or similar name) within the world folder. Activations are stored within player data.

Perfect! Thank you, I'll make sure I keep a backup of this going forward.

I just ran into this today where I upgraded the server and client modpack from 1.18.1 to 1.18.2. Where are the coordinates being saved to? I looked at the config folder for waystones, but no coordinates are in that file.
Assuming I messed up in the upgrade, what do I need to do to preserve the waystone locations?

Closing since this was likely a mod conflict that's been solved since.
