Currently on Neoforge 1.21.1, with HUD Compass, JourneyMap, JM-integration, and Waystones.

After reloading a world, waypoints in the game go invisible to the HUD until you manually hide and unhide each waypoint (one by one, can't use the "hide/unhide all button). It seems to be the only way, i've tried turning on and off JM integration in compass settings, but that doesn't do anything either.

Here's a video of the issue if you want it:

Hm. I'll have to look into it. It is possible that the 1.21 version of journeymap no longer gives "waypoint added" notifications when reloading. If this suspicion is true, I may have to manually list the waypoints when loading.
I don't know when I'll have the time & energy to take a look but soon.
