Just bought this from the marketplace today to play with a friend. At first the textures weren't loading then I reinstalled minecraft and they worked. But the problems didn't stop there. I was having a really weird issue I've never occurred with minecraft before where there was this "lag" that prevented me from opening inventories, destroying blocks and mobs would be frozen. It would fix itself within a few minutes but this glitch was very frequent. What is the reason for the glitch and how can I fix it?
