[2.0.73] rendering issue: some of the space platform tiles are not rendered

[sben]

See the following video:



Space platform tiles are not rendered in two disjoint areas:
- below the rocket turret in the middle
- below the solar panel on the side

The tiles are there.
When trying to place tiles there, blue highlight appears and placement gets ignored (I forgot to record this part).
When hovering a [Q]-selected ghost in the affected area, the tiles are revealed.
When loading the savefile, the tiles are rendered as expected.

Reproducibility:

Noticed this first time like 2 months ago and experienced it about 5 times, but I am not sure how to reproduce it.
I think this might be some race condition between the simulation and render threads.

I think this might happen if
1. [Ctrl+X] cut ghost structures from the front part of a space ship
2. remove some of the platform tile ghosts in this area by [Alt+D]
3. place the cut parts from step 1 shifted by few tiles in a moment when space platform tiles are getting built (animated) near the placement location
4. the non-rendered tiles are always located where built tiles meet ghost tiles

I am not sure if these steps play a role to reproduce, but as far I remember, these steps were in common every time before the rendering bug happened.

Thanks for the report. Without some kind of steps to reproduce this I’m afraid there’s not much we can do.
