I was out walking to place item frames in villages with maps in them so that I could locate the villages from the copy of these maps which I held in my inventory.

So I placed an item frame in the first village and attached a copy of my existing map to the item frame and at this point there were no problems.

I walked on to the next village where I would place my second item frame with another copy of my existing map. I reached the 2nd village and placed an item frame and attached a copy of my existing map to it.

Here is where the problem (BUG) started. I left the 2nd village and noticed that the white marker indicating my position was completly gone on the map I was holding which was another copy of the two that I had placed in the two villages.

So I tried to resolve this by moving back to the 2nd village and removing the item frame there with the map in it. When I did this the green markers was still present on the copy that I held (like reported bug MC-73) but this didn't help, the white marker was still gone.

After that I made more copies of my map to check if the white marker would show up on them but it didn't.

Instead the green markers were still present on all the copies of this map that is, even the marker that I had removed in the 2nd village by removing the item frame. Exactly like bug MC-73.

What I had expected to happen was that when I placed one or more copies of my map in item frames I would see green markers on the copy which I held and of course also my own location (the white marker). And again what happened was that the white marker disappeared on my map after placing two item frames with copies of my map. Additional bug was MC-73 (green marker still present after removing second item frame with map copy in it).

When I logged in again both green markers was gone and the white marker had come back.

I logged in again and I went to the first village to remove the remaining item frame. I removed it and went for home and I opened the stack of copied maps but now the green marker was still present after removing the last item frame from the first village.

I logged in again a fourth time and then as expected the green marker was gone (marking the first village)
