Objects that have not yet been triggered by scripts should not be visible through distant land
I found that OpenMW's distant land view tends to render also objects that should not yet be visible, because they should appear in the world after some script activates them. It happens with several mods, but an easy way to reproduce it is by using this mod: https://www.nexusmods.com/morrowind/mods/52513 The mod adds a Battlespire hovering above Sadrith Mora and, once you reclaim it through a quest, you can use it as a house and as a travel option, which means that you can teleport the Battlespire above any major city of Vvardenfell. OpenMW, with this mod enabled, renders in distance the Battlespire above any city. You can easily spot it from Seyda Neen looking at Vivec city, for example. This doesn't happen on MGE-XE. Tested on OpenMW 0.48. Windows 11.
