In the quest "Caught in a Net", found in Idathren at the Sadrano Manor and started by asking about the topic "common thief" to Belera Veran, after the player completes the route where you help the Indoril Spy Boderi Ulen escape, she tells you to meet her in Velonith to receive your reward. After arriving there she is nowhere to be found, neither around town or in the local eggmine. Possibly a bug that appeared recently since it was notified to me that this didn't happen in older versions.
All vanilla faction questgivers have NoLore. In TR, many of them don't. An ideal solution to that is to go through every questline, check when quests rely on questgivers' generic dialogue (for example, using specific topics for giving directions), and add custom lines to those questgivers.
Two changes that should be done after AT is NPCed:
Rebalance of gold and ordinator aggression values in Q1, which depends on the amount of pilgrims in AT.
I expected that Falura Andavel, the Q2 target, will be placed inside her house, but instead she's in a tavern and her house is locked. Adosi Biran's advice in Q2 should be changed to account for that.
Back when we were going to release a DoD bugfix update separately from LA release, I tried to avoid using "Talked to PC" function so players who update TR mid-game could still receive new quests. Instead, I added a "greeting" local variable which was set to 1 in greeting. It was made in 2 quests: Material Matters and Rivaling Alchemists. Now, there's no reason to keep it.
gold_dae_cursed_001 is an unused vanilla item, but TR adds it in a couple cells, Yamandikal, Sanctum and Anashbibi, inner shrine. This item caused an error for me when I tried to pick it up: "Did you add a new type of gold? It needs to be added to the TES3Container.cpp file."
The "Guide to Firewatch" includes two maps, a map of the city, and a map of the surrounding area. The first map shows up fine. But the second map just shows up as a white box.
I wanted to upload a screenshot, but it's too big. I posted the screenshot on the troubleshooting channel on the Discord.
