Ritual map overlay icon didn't reappear until reaching the Ritual

There's something funky about Ritual icons. E.g. Expedition and Shrine icons can be seen on the minimap from many many screens away as you approach them.

I found a Ritual altar. I didn't click it, moved many screens away and it eventually disappeared (normal). When I later tried to come back and find it again, it took forever to find. It didn't reappear on the overlap map until I could literally see the Ritual on the edge of my screen.

Walking away from it again it took several screens to disappear once again. So the bug may be detection on approach. If it matters, I was coming at the Ritual from top to bottom, on a Hidden Grotto map layout. It was the 3rd/final Ritual, i.e. I had run the other 2.

There was an Expedition somewhat northwest of it. Now that I think about it, it could be map overlay icon priority bug. I.e. Expedition was still the icon allowed to display as I walked away from it, causing the Ritual to appear at the last second. And then when i walked away from the Ritual, the Ritual icon remained because that one was the most recent/priority.


Edit: after further play, I believe this occurs for all mechanics with a map overlay icon. Visible from far initially and visible far behind you, but once it disappears for the first time, finding it again it has to be on your screen. I think this even affects Town Portals. haha
