This rock failed stage 3 pre-polish. It was actually my favorite rock in the batch. Before tumbling, I cut off problem areas with my lapidary saw from CabKing, then I shaped it a little with the grind wheels. It went through stage one 3 times until it was smooth and flawless. It made it through stage two in great shape. After 8 days in stage 3 : pre-polish, I pull out the rock and I am totally disappointed. In the video below, you will see why......
I think the green areas are mossy areas, and that is possibly the reason for this issue.

Sorry to see that happen. This happens to my rocks more than I like to admit. Plastic pellets as tumbling media might help to keep this from happening.
I have similar issues with some material, especially tepee canyon agate and some local Black Hills jaspers. Want to blame micro fractures. Some finish great, others hit a certain stage, usually pre or polish, and come out looking like they jumped off a cliff.
I have more than enough beach rocks ending up like that. Some veins are really soft and they hold up ok in step 1 and even step 2. Some just reveal the pre-existing cracks that were hidden quite deep at a later stage. I just avoid tumbling these types of rocks. I don't have extra attachments to my self collects, especially when they don't behave...

I have experienced a few crazy rocks as well that went into the final stage a 10 out of 10 and came out looking like a 1 out of 10 stars.

I’m curious what kind of rock is that exactly? Local find or one that you bought? I’m asking because it looks familiar, like ones I’ve found around here.

This was found in the shallow water of the Colorado River in Bastrop County.
Unfortunately that rock was never going to make it. The quartz veins are healed fractures, that never really heal well enough. It is a shame because it would have looked amazing! You could try to stabilize it if you so desire.
I can't tell if thats some Gneiss Schist, or that Schist is Gneiss. All I know is don't take it for Granite
