New world

If I fish in a cave and dive out the realm crashes.

Iv been fishing and trying to leave after I get some bows I leave and realm crashes buy freezing and either kills me by drounding in the crash or turns to knight when I can move when game froze lagged out crash realm. Tryed loading in with phone and doing the same. Also crashed the realm by leaving the cave after fishing.  

Could be connected to my other issues and having realm drops and save losses. Typically it has been making a save after I die from a realm crash. So I go back the 38 or 40 mins. I don't know if this can help Me I hope I'm not wasting you time.
