While playing the Windows 10 version of Minecraft over the last couple days I have experienced several problems on a realm I have. The first being all of my paintings have disappeared and wont let me hang them anymore, I've had multiple horse and mules just vanish before my eyes, and the last being nether portal connections being very unstable. I've tried linking ones in the overworld and the nether through coordinates and it doesn't work, or just using the ones that have been perfectly linked and then they send me to a random set of coordinates and create new nether portals in both the nether and overworld depending on which one I just entered. It has sent me just a couple blocks to a new portal it has created or all the way up to 10,000 blocks in one or both directions. I've tried breaking or, again, linking them but just seems to stay the same. Would appreciate these problems being fixed.
