My sister went through a nether Portal and spawned on the other side without one... Not only was the nether Portal linked together with another one on the other side (which it did not take her to), my sister is permanently trapped in the nether because of a bug...

This is not the first time we have experienced issues with nether portals, as before she was teleported 1000s of blocks away from a nether Portal I linked... It took her hours to get home, I really want to know what is going on because dealing with this issue is a nightmare...
