Bat!

Hello!

I just finished this achievement by using these bats:

/way 57,3, 61,3 Dreadbat 1
/way 60,4, 61,2 Dreadbat 2
/way 64,1, 62,1 Dreadbat 3
/way 31,9, 59,2 Dreadbat 4
/way 25,1, 37,6 Dreadbat 5

1. 
   
2. I had to ride a few of them more than once for them to count
3. 
   
4. Sometimes the credit was awarded immediately, while in other cases, it was awarded randomly in the middle of the flight, or right on landing.
5. 
   

Bat that was supposed to be at /way 56,3, 62,3 wasn't there for me at all.

TL;DR bugged, wait for fix, unless you want to test your luck or spend loads of gems.

found another bat besides those people list.

/way 21.68 50.23 The Shrouded Asylum up at the tower.

counted as a ride after landing.

Found another bat at /way 35 35 that did the trick. Doesn't appear to be mentioned in the other comments.
