Well i did not have a fps drop,@xSoNz, @JimmyBlether - are there any common factors with your experience of this bug? e.g.:
- Just re-loaded the save.
- Having loaded in very large techs before hand (maybe in a different game mode).
- Substantial FPS drop (for no reason), before seeing the glitch.
- Graphics set to "fastest".
and I was at start so i didn't really have a large tech.
The rest are true.
