for some reason while instamining near a river i started getting quite a lot of frame drops as well as this small black thing flashing on the screen
how to replicate:
1: make a new world. or join an old one. doesn't matter
2: get an efficiency V diamond shovel
3: go to a river with a lot of sand in or near it
4: dig the sand to find the flashing blocks
