It seems that since the last patch went live many achievements (based on counters or multi-part) are unattainable. This covers both solo achievements, as well as raid achievements. Some of the example ones are:
- Yak Attack
- Nerf Scrapbots
- Three Car Garage
- In His House He Waits Dreaming
- Aberrant Behavior
Players I have been in raids with have reported more such achievements, so this is not only my observation. I have participated in regular Ulduar 25-man achievement runs via Openraid for the last couple of weeks (for non-meta achievements). I already got most of the achievements in Ulduar, and was there to help others, so I know the way those achievements should be done, and still they were not attained by others who needed them.
An example of Yak Attack is a good one. I went to Niuzao Temple in the proper phase to attain this achievement, as a tank on my druid, with a friend to heal me. We have gathered enough mobs and allowed the yak to kill them, and have not received the achievement. Absolute proof of this being bugged is the fact, that a random mage asked to join us, and when all three of us were in a single group and next to each other, the random mage got the achievement, whilst me and my friend did not. Therefore it seems the bug affects some players, but does not seem to affect others.
Another example is a friend of mine in the Ulduar run, who was trying to get Three Car Garage, and despite the fact he took the chopper (the only one he needs) in the last three runs we did there, the chopper part of the achievement was not awarded once Flame Leviathan was down.
If a counter-based achievement is tracked, you can see that it is bugged for you, if the counter won't increase (for example if you need a certain number of mobs to be killed) and remains at zero.
If you have come across cases, where multi-part/counter-based achievements are unattainable, please share your experiences, so Blizzard knows this is not an isolated case.
Hoping for a blue post that would confirm that the support team is aware of this problem, and fixing it, as achievement runs in many raids are now seriously in question...
Thank you in advance.
