+1 @Ildun , those daily Ashlander quests in Vvardenfell used to give a good amount of rapport gain for Mirri, and they don't anymore since U33 came out. You don't get any rapport from them if dismounted either, it's not specific to being mounted, as far as I can tell.

Also, on two of my alts which don't yet have max rapport with Mirri, but HAVE (I'm fairly sure) completed the Library of Vivec (vvardenfell), visiting the library there does not give rapport either. Likewise, the museum collections in Senchal (Dragonhold/Southern Elseweyr), Riverhold (Northern Elsweyr) also don't work, nor does the Psijic Vault in Artaeum, nor Kari's Hit list collection in the Thieves den. (These all used to give +5 rapport for Mirri, once per day, 20+ hour cooldown each.)

The Orsinium museum (Wrothgar) does work (normal +5 rapport gain), as does visiting the Brass Fortress or entering a Daedric delve (+10). Something inconsistent here.

Solitude (Bard's College) museum doesn't work for rapport gain, but I don't think it ever did before U34 either. Mirri does at least SAY something there though. Likewise, the Murkmire Calendar doesn't do anything for Mirri's rapport, and never did in the past either. (She doesn't voice any interest in this location.)

Mirri still approves of you killing goblin scum and reading books (+1 rapport each, 5 min cooldown), and still disapproves of harvesting butterflies and torchbugs (-1 to rapport, seems like she used to care about other insects too before U34 tho?).

So basically two of the main ways of gaining rapport with Mirri are broken in the new update (Ashlander dailies and most museum repeat visits, although I don't know about first-time visits). I don't know yet if this is an issue with the companion coding or with Account-wide achievements...

Update: Ashlander dailies do still give rapport gain, but it's very inconsistent. More testing needed to pin down why it doesn't work sometimes.

Interesting. It looks like it's inconsistent, works sometimes for rapport gain) and sometimes not. I just had a rapport increase on my PC/EU character from one of these Ashlander dailies. I've had problems with it NOT working on my NA characters tho.

Note: whatever the problem is with the museums not giving rapport gains, it's not an account-wide achievements issue. I tested it on my PC/EU account (with only one character), and the same issue is occuring there as on PC/NA.

@LoneStar2911 also reported issues with not gaining rapport for Mirri from the Ashlander daily, in this thread (March 21).

@Ildun, after further testing with two alts on PC/NA, I think you're right. When turning in the Ashlander daily, you have to dismount first to get a rapport gain for Mirri. Being mounted means that you don't get any rapport when completing the quest.

Update: one of my characters is bugged and doesn't normally get rapport even if dismounted. It sometimes works for her though if I also remove the Ring of the Wild Hunt. I don't know if that's the problem or if she just has a week-long cooldown instead of the normal 20 hours.
