Brief Description:
Acrobatics MCMMO isn't giving XP despite landing on different blocks very far away and waiting a good amount of time between each fall.

Instructions:
1. Do /wild land (in mining world)
2. Build a cobblestone pillar 64 blocks high
3. Jump off of the pillar (I wore FF4 boots)
4. Run 150+ blocks, or do /wild land again, and repeat the steps

How many times did you recreate this?
10+ times

Result:
No acrobatics XP was received after taking significant fall damage

Expected Result:
Acrobatics XP should have been gained

 

The steps I listed in the bug report were what I was doing:
1. Turn off /fly
2. Do /wild land in mining world
3. Build 64 blocks directly upwards (I used cobblestone)
4. Jump off of said 64 block tall pillar (I was wearing FF4 boots)
5. Repeat steps 2-5
I did not receive acrobatics XP when following these steps

 

Update:
I repeated my experiment at different block heights and that is what seems to be the bug on my end personally. Any pillar I build up as long as it is 32 blocks high or less, gave me acrobatics xp. However, once the pillar hight exceeded 32 blocks (33+) I ceased receiving acrobatics XP. After jumping from 33 blocks or higher, the bug would kick in and I would stop receiving XP from jumps higher than 20 blocks. No xp was gained from this point further until the bug seemed to be reset by a fall of 16 blocks or lower, after which xp could be gained from jumps 32 blocks or shorter again. To explain, these are the steps I took and results I received:
1. Remove /fly
2. Do /wild land in mining world
3. Build cobblestone pillar 32 blocks high
4. Jump off of pillar
Result: XP gained
5. Do /wild land
6. Build cobblestone pillar 33 blocks high
7. Jump of pillar
Result: No XP gained
8. Do /wild land
9. Build cobblestone pillar 32 blocks high
10. Jump off pillar
Result: No XP gained
11. Do /wild land
12. Build cobblestone pillar 24 blocks high
13. Jump off pillar
Result: No XP gained
14. Do /wild land
15. Build cobblestone pillar 16 blocks high
16. Jump off pillar
Result: XP gained
17. Repeated steps 2-16 and results remained the same

In essence, the bug in my experience appears to be due to block heights (or fall distance), though I did not personally roll during my experience so I'm not sure how @JaredOxO explanation of a bug for rolling ties in to this, they may be two separate bugs.
