Its still working fine for me so this might be a bot issue, or a system issue ...
Though its not afkable:
"90 Minutes until first stuck lvl 11 Durotar - "Watershed Patrol" -> "escort Grandmatron Tekla"
130 Minutes till second stuck lvl 14 Durotar - "the Wolf and the Kodo" - one of the accounts does not leave vehicle "wolf"
lvl 23 stuck at Vorsha the lasher Ashenvale (one bot started "Vorsha the lasher" an escort quest, which the other one did not accept but followed the npc to the last spot the npc
was moving and stayed there trying to pick up the quest from the npc which had disappeared after a while, not going back to the position where the quest starts) After that quest they tried to get riding lvl 20 - I wrote a little about that, too .
lvl 37 stuck at darkmist extermination dustwollow marsh (got seperated in brackenwall village one of them turned "darkmist extermination" already in and was trying to turn in the next quest,
while the other one was trying to turn in "darkmist extermination")"
There was another stuck at 33ish, and at least 3 more until 55ish, also using RAF makes you level up so fast that you wont have enough money to buy riding skills at 20 and 40, so the bot will go to the riding masters and wont be able to learn in, for some reason i ended up in Tanaris with my lvl 27 druids, because they went there by foot, after they were not able to learn riding in Mulgore for the 5th time, and of course got killed on their way over their dozends of times.
The stucks are acceptable, but the "learning riding" stuff really annoys the shit out of you, especially the bot does it after you stop and start it again, so I recommend having enough gold for the first riding skills - maybe farm some copper with level 19, but you should really be around, or you will simply lose the RAF bonus because of the stucks or most of it - depending on how long you are afk.
