These blocks do not drop themselves when mined with pickaxe or bare hand, they also instantly break even with no tool when left clicked with no drop. There's also no suggested tool to break it with WAYLA.

Steps to reproduce:

1. place down any 1024k+ storage blocks down in the world
2. try picking it back up with pickaxe or any tool/barehand.

Additionally, not sure if related:
Was not able to reproduce this in single player world, but on a TNP5 server, these blocks will automatically break themselves with no drop when when placing just 1 of them next to an online ae2 cable, or placing a co-processing unit next to it.
