@Grabeck Thanks for flagging these! On the city banners that's not a bug, the banner currently has a fairly large placement footprint, which is likely what's causing the "too close" restriction near the shuttle. It's worth revisiting though, and we'll look at adjusting it to be more in line with how street lights are placed, which have a much smaller footprint.
On the indoor/outdoor trees from NS not placing outside we'll look into that one as well and see what's going on there.
As for more city decorations in general, that's a fun idea and always good to hear what players want more of we'll keep it in mind.
Appreciate you taking the time to report these and suggest improvements keep them coming!
Best,
