1 - Loading into a world in any mode is excessivly long, it takes about 5-10 minutes to load into any world.

2 - After playing for a while, the games stops loading terrain leading to white world bug where the whole world is transparent.

   2.1 - During white world bug, you can teleport, adjust hotbar, go through options menu but once you teleport you can't move or jump, it looks like you are frozen in space.

   2.2 - in this state if I try to save and exit, the saving screen progress bar gets stuck at almost halfway through and stays there for a really really long time, I mean one time I left it running and went to sleep and found it done the next morning.

3 - There is a bug where if I backed out of the campaign menu to the main menu it does a loading for the main menu that takes ages aswell, is it loading the buttons?? like is every button like 1GB?
