Guild Wars 2

Upon clicking the achievement, it says:

Reward:
[AP] +5
Loot Bag

Upon hovering over the AP icon to check how repeatable it is, it says:

Repeatable +1 [AP]
Total: +1/15 [AP]

This is inconsistent with other achievements, which say Repeatable +5 [AP], indicating that one needs to repeat the respective achievement three times to get the maximum AP count from it.
Also finishing the jp 60 times seems more likely than 300 times for 15 AP.

I believe it’s a bug in displaying upon hovering over the AP count for Point Breakdown of the achi in question.

edit: for some reason the on-hover tooltip showing Point Breakdown does not show in screenshots. Hover over that big [AP] +5 to see what i mean.

Yeah, I noticed this too, so I decided to do a full 20. You get 5 AP when you do the 20 (6/15 AP total). Then the achievement resets again, and you get 1 point for the first run again (7/15 AP total) and then goes back to showing you get 5 for finishing 20. From this pattern, completing 20 should put me at 12/15, and then 13/15 for doing the first of a set. Finally ending with 18/15 from finishing 60 runs. I’ll check and see if it actually truncates it to 15/15, which it should (I’ll finish it by tonight and edit my post in a few hrs).
