[Pard] [2.0.23] Background simulation problem with SA

[nincompoop]

Two small errors as far as I can see (I did not find this reported earlier):
During game launch when the background simulation plays in two scenario's there's a small error I believe:

- Scene with the engineer destroying a biter nest with personal laser defence. The path he walks is still the same as pre Space Age but now there is the space age logo added underneath in the gameworld upon which he gets stuck.
- Scene with the biolabs and all the science bottles on belts. The spoiled removal belt lane has an extra singular underground belt added in the middle of the belt that does not connect to anything. Visible when you move the menu from the center of the screen.

Not very important but I thought I'd mention it.

Actually, I'd like to add that the artillery train resupply scenario has the left lower most artillery cannon not being supplied due to the inserter being too far away from the train to unload.
