Hi, It's me again. Sorry to keep on submitting.

When I use the Neighbour Updates Overlay, the overlay outlines seem to misalign with the block grid entirely. The numbers, however, remain on the cooresponding blocks, but the grid doesn't.

MC Version: 1.15.2
Mod Version: Minihud-fabric-1.15.2-0.19.0-dev.20200121.203515

Also, is it also possible if you can give me a sort of run down on what the numbers correspond to?

Most of the vanilla debug renderers are broken like this in 1.15 (might be because of where MiniHUD currently renders them from...).

The numbers in this case are the amount of block updates at that location in... some amount of time, I don't remember if it's per tick or what (don't have the code at hand atm).
