Few things I noticed while playing about with my new ultrawide setup:
- Zoom doesn't seem to be limited in how far you can zoom in
- On maximum Zoom out all maps are too small to cover the entire screen, biggest offender being this one
- On some maps cheat items can be seen
- Fire outside of nowhere
"Fire out of nowhere" is most likely related to crashsite effects when the save file for the background was being created. It does not cause any harm.
With the zoom, i think its better to have it as it is right now (no hard limit for the zoom) as most likely any zoom limit will make someone unhappy. Nothing really broken here.
For the cheat items and the remaining part of the infrastructure for the background simulations, there had to be a reasonable limit of how large this scene should be created. If you can see more than that and you do not like that, you can always disable background simulations. Nothing broken here.
