The quest breaks if you interact with Vantus between giving the goods and returning to the captain. Instead of unique messageboxes, you receive a bounty and Vantus doesn't move to the ship.
If you spend too long in Bel-Betu's private quarters, then his skeletons and himself start attacking you. Makes sense to some extent (though not sure why he cares so much about his old worldly possessions), but why doesn't he stop sending frostbursts my way after I have talked to him?
An Andothren MG quest (TR_m4_MG_Ando_3) sends the player here to get a book from the master of the tower ("TR_m2_Nisa Darythi"), but there is no one to tell him how to get to him. Players starting in Andothren will probably not know how to find a Telvanni wizard until they start exploring Telvanni lands.
- Discover Etana Egg Mine. Talk to people. Obtain journal TR_m4_Om_RemnantsResdayn 50: The miners in Etana Egg Mine are at a loss about what to do with a cursed Indoril artifact they found. The foreman wants them to remove it by hand, but the miners are frightened and hold out hope that the Andothren Temple will send Ordinators to deal with the task.
Quest TR_m4_Om_RemnantsResdayn ("Remnants of Resdayn") can well be obtained by randomly discovering Etana Egg Mine. But then the quest starts at stage 50, whose journal entry does not mention where the egg mine lies. This makes it hard to find it afterwards. I suggest adding "-- west of Menaan --".
In this quest, Neel Gymont asks for 4 ingredients, two of which are bittergreen petals (ingred_bittergreen_petals_01) and hypha facia (ingred_bc_hypha_facia). In the Aanthirin and Roth Roryn, the former are very rare while the latter apparently non-existent. Thus I suggest that the quest add the topics "hypha facia" and "bittergreen petals", and that alchemists and scouts in OE and Andothren (or maybe on the whole map 4) have some moderately helpful responses:
I've seen this in "Barendreth, Lower Level", but it might well be happening in the other parts of the stronghold as well. Why shouldn't ordinators summon clannfear? First, it is weirdly unorthodox for a bunch of ordinators to summon bad daedra. But gameplay-wise, it makes the situation far too confusing: To the player, daedra are daedra and call for the sword. There are some hostile dremoras in the stronghold that clearly deserve this treatment. But attacking the summoned clannfear turns the ordinators hostile, which is hardly the intent. PS.
One of the most common questions is 'where can I sell my stuff" or 'which merchant has the most barter gold'
I think an existing smith could get some minor mercantile/barter gold/inventory tweaks to be a high end merchant. Not as rich as the Narsis one, but better than what they have now.
