Weird things are happening, need understanding.

I got my legacy seed back from ps3 seed is goo, after converting it successfully I've been playing it for 5 months now this is happening. World spawn moved 100 blocks from world spawn location. There's been a few times a bio will try to spawn in and then disappear a second later. The wandering traveler I haven't seen him in about 2 weeks. Farms have randomly gone from being active to inactive unless I'm about 4 blocks around. I didn't complete a trials chamber and when I went back in all the loot has been canceled out.
