I've always had this issue, but it's recently gotten worse. At my subway/metro stops with multiple floor levels, the unusually large cims don't disappear at a certain distance like they normally would at single-level stops. I remember reading about this somewhere, but I can't recall if it was linked to cim models from the Steam Workshop or if it’s related to a gameplay mod.

Does anyone have any insights on this before I go find the mod? Your help would be greatly appreciated!
