0009551: Floor grates built over water that freezes de-construct when the ice melts
Fairly self explanatory and probably related to other bugs with ice and constructions.

Floor grates built directly over water that freezes (as in, 1-z up) de-construct themselves when the ice melts again.

The grates were built when the water was still water, there might potentially be different behaviour if the grates are built on top of the ice but I haven't tested.
Build some floor grates over a tile of water and wait for the temperature changes.

Were they still supported from elsewhere when ice under them melted or was only that ice holding them?

Melting ice deconstructing things is a longstanding bug: 0003320
