After discord discussion, a few more edits were made to the exterior of Nurstra's complex in SH, most importantly adding a secondary tower to the mesa.
The Vantus Mine Key, tr_m1_ito_fw_keyvantus01, which is given to you at the beginning of the quest "Miner Problems", is supposed to open the locked door to Vantus Mine: Packing Room, but it also opens the locked upstairs door in Firewatch, Vantus Manor, allowing you to access the bedroom and steal everything inside.
With all the beautiful new Dunmer (and other) armors that have made it into Data in recent years, it would be cool to integrate them into commonly-visited Mainland settlements in preparation for Grasping Fortunes - Especially the quintessentially Dunmer Guar Hide, Kagouti Hide and Alit Hide sets. These sets are also mostly absent from most merchants in Narsis and other GF settlements, as the Alit and Kagouti sets were added into data quite late in development, after most interiors were made. Smiths and merchants in obvious places like Old Ebonheart, Firewatch, Andothren etc.
The farmlands south of Hlaalu Ferry and Kuriki should have dialogue about the Bandits in Kuriki problem. This quest was completed prior to NPCing of that area, so the farmers, the primary victims of these bandits, have no lines under the "bandits in Kuriki" topic. This isn't a huge priority, but if the player decides to go to the farms south of the cave, they might find it odd that the farmers have nothing to say about the bandits.
While asking around for the crazy half-naked Dunmer in Gol Mok, I was ambushed by a woman named Duvlas. She appears to have worked with the the [sic] smugglers who stole Kassad's package from Hammerfell. On her body, I found a note that indicates that the smugglers are hiding somewhere close to Gol Mok. It appears that the smugglers are quite sloppy and sometimes they leave their rowboat just outside their hideout.
As title says. The propylon chambers of some strongholds that currently exist in mainland (Barendreth, Hlorandus, Othrano, Romayon, and Volenfaryon) link to incorrect strongholds and don't reflect the current planning. In some cases, the propylons for the strongholds don't even exist, or are missing scripts.
