I ran into the same bug today.
Here is a savegame with exactly the moment where it happens.

In your save the bottom right tile under the cryo plant is ghosted for only ice platform which isn't valid for building cryo plants on. When the robot builds it, it detects the collision and removes the ghost.

The real question is: how did the ghost end up on top of a "place ice platform" tile ghost and not a "place ice platform, and then concrete" ghost. When I shift-click place a new cryo plant there it correctly puts ice platform + concrete and when both are built, the cryo plant is then built.

Nice find, I didn't realize this.
So figured the blueprint is the root cause. When I print it down it is already missing at that corner (even though concrete and ice platforms are not part of the blueprint). However if the car is removed from the blueprint it's working just fine. This is probably connected to a bug I found earlier that I never reported that is when i place a ghost car on ghosted heat pipes. Placing the car may also remove the heat pipe ghosts sometimes.
