Bug/Issue Achievements - All Seem to be Working! Except...

I can't seem to get Destroyer of Worlds to trigger.
I have no idea what's needed for it.

The achievement says, "Move a planet's worth of blocks".

The game files mention,
"name" : "planetblocks"
"triggers" : "item.category.block"
"op" : "atLeast"
"value" : 10000000

Someone that may've been mistakenly identified as a "dev" on Steam claimed you need to completely destroy all blocks on a planet, regardless of size. I found that doubtful but I tried it. I have destroyed an entire planet now, leaving not a single block remaining (including destruction of meteors above it). The achievement didn't trigger.

I've also likely destroyed at least 10,000,000 blocks in the process of this. I didn't pick them all up (I had to mod them to not drop blocks or I'd have frozen up from the amount of entities on the screen).

I have however juggled block stacks (1000 in each) more than 10,000 times by breaking containers and then relocating the items, over and over. This didn't seem to do it, either, which seemed the most likely to succeed.

Anyone else have any ideas or is this one bugged?
