Inifinite loop Ingenuous Rock falling over and over

This usually happens when a material goes through phase change. I've seen it quite often when generating steam from contaminated water where you get bouncing balls of dirt that constantly grow in mass every bounce.

I had a similar problem - dirt blocks bouncing up and down on two spaces next to each other. This was material from deconstructed tiles

Further to this:

Dirt is affected.

No idea what started it, seemed to be falling out of my large battery/wire square.

Few grams at a time, and it tied up 1-2 Dupes constantly while they fed the research bench a few dozen grams at a time...

Bonus video!

I dismantled the battery, the wire, the tile below it and the dirt below that. Nothing, still infinitely spawns a few grams per second.
