Workers constantly being crushed after level 50?

[Violent Rainbow]

I swear to god the chances of a block falling and crushing workers increases 8000% the further you get through the game, like I'm on level 52 now I WAS trying to reach 150 nights achievement but I'm literally losing half a dozen workers AT LEAST every single day just form being crushed! And there doesn't seem to be any way to prevent it, like I'll tell them to work on the blocks at the very top and somehow it still crushes them? Like wtf is this? I'm not even just talking about those pale rocks that ALWAYS fall, it's like every rock dos it now!

A lot of rock types can fall during the earthquake event (I forget what it's specifically called). I think only the indestructible blocks can't fall. Another reason to mine top down.

Unseen big boulders will drop the moment you mine the block below them, in cavernous biomes. Don't mine upwards unless you've already seen the block above, just to be safe.

I believe there's also sand-blocks that fall down in a similar ways.

Then there's the earthquake event as mentioned, but that is only occasionally.

Hi, seems there is a bug. I also noticed this. In the cavern-levels when an enemy captures a block and gets free the block changes to a boulder block.. But not every time and maybe only when workers are also digging (from below).
In any case, it is very difficult to see what is really happening

I do not think it depends on the day 50. For me all was fine till day ~80. It seems it happens more often when you max your workers above 16. In my case it was when i had 20/20 workers. Later on i lost a worker (elite) and than it seems it happens less oftern.
But i did layer for layer than till day 150, so not sure about this at all.
