@Minecraft @MojangSupport Ok. So, current beta (1.15.0.51.70) has broken all forms of mapping. After creating a map, using it creates 4/4 map level and can not be "expanded" and when put on a frame, becomes pink and cursed and cant be moved from slot. Similar to bee nests.
If you think you've found a bug, please visit https://bugs.mojang.com/secure/Dashboard.jspa … and report it so that the developers can see. ^JS
