I don't know why it started. Recently I have been having problems where some time into playing there is always a point where the mobs freeze, I can't open chests, and I can't pick up or drop items. So I tried looking for a fix. Someone suggested maybe I wasn't giving minecraft enough ram, so I went to the JVM arguments in my launchers setting and changed the 4gb to 8gb. It worked fine when I loaded into the world, except that I still eventually had the same problem of all the mobs freezing and such. Then I tried loading again and that's when I started crashing on loading into my save. I tried changing back the 8gb to 4gb, but it still ended up crashing. Help is Appreciated.
