The circled places are terrain traps: You can't get out without magic. Probably not a bug in most places, but Andothren is going to be one of the very early-game locations, so this is worth improving. If you feel creative, maybe add some hideouts there that make urban exploration somewhat worthwhile.
While at that... flora_bush_01 at (2022, -132136) is floating. This is right near the Andothren Temple entrance.
When I first set foot inside the "Black Orc Tavern" in (Bal Oyra? Most northeastern town on the mainland) my first thought was that it was closed or abandoned. Felt very empty and lifeless.
I'd recommend a significant amount more clutter, even some messiness. And perhaps a moving NPC.
I don't want to nitpick, but it was very noticeable.
Something needs to be decided about whether to edit/disable it in a plugin (TR_Factions?) or remove the TR additions and just let recommended third-party fixes disable it, but regardless of that, here are old notes on issues with what TR adds to block the original Bloodmoon dialogue:
This quest kinda finishes, and questline continues, but it never removes from journal and Gindaman still tell you that you need give that soulgem to Absolon (looks like queststage 50 not properly working) Also, during queststage 40 Absolon, when you return soulgem to him say same phrase that said when you give that gem first time, this is kinda odd.
tr_a_nord_shield_03 seems to have the wrong edge texture-- should it be tr_a_nordic_wood_shield_back.dds? (same for shields 5 and 7). They seem to be using the shield front texture.
