TU43/CU33/1.36/Patch 13, TU45/CU34/1.37/Patch 14
We do some transformations to the world, mining in Minecraft.
During mining blocks it seams that if more than 128 item-blocks is not picked up by the player. The game starts to lag and stutter at this point unpicked up blocks despawn. The time is always less than 3 minutes.
If this is a way to make the game less lagged I guess a better way of solving the lag issue is to fix the lagged-water bug created in TU33.
This was observed in single player, offline play.
I did not notice before but Beacons also loose the effect for a short while. One or two seconds.
