Map markers are green when they have been visited, but if you quit and rejoin and are far enough away from the map markers then they become black

Mega_Spud, the map marker that you're showing as the problem is still on your maps, it just appears black. You can see the map markers better when you're in the overworld and the map markers are in areas of grass and sand. I've attached a screenshot that shows problematic map markers in grass-dominated areas

Just tested the map markers on a flat world with a 4/4 level map. Upon reentering the world in v1.0.0, the map markers that aren't in my chunk are blackened out rather than just removed like back in v0.14.3. IMO I feel that the blackened out map markers are an improvement because it gives the sense of "Oh hey, this is where your map marker was but it might not be there anymore if you decide to go back over there".

Hi, just checked and it does affect version 0.14.3 on Windows 10

@Kaleb The bug still exists in 0.14.3 in the way that you and I described

I've added a video going through Kaleb's steps to reproduce the bug. You can see at the beginning that I drop a 64 stack of cobblestone onto the ground and replace my final inventory slot with 16 cobblestone. Collecting the previously dropped full stack fills my inventory, and the extra cobblestone disappears.

Video of Win 10 Beta Map Marker bug. There are 2 green map markers in the video: the one directly on my player marker is my home base and the one on the upper right of my held map is the marker of a far-off village. Upon reentering the world, the village map marker disappears. Not shown in the video is the fact that the map marker reappears ONLY if I walk back to the village first.

This problem also exists in the Win 10 v0.14.0 release. I ran into the issue when maps I had placed on item frames did not appear on my map upon reentering a world. Here's a video showing a green map marker disappearing
