Greetings,
My WoW did also crash after 10-20 minutes of using "questing" with Honorbuddy.
I tried to search for any solutions on the forum, but didnt came to one.
So I tried to figure out myself what I can do to resolve this.
And for me this worked out, so I wanted to share with you guys to atleast give it a try.
1: Clear all the Cache, WTF, Add0ns ( yes delete everything inside these folders ).
2: Run the "Repair" from the WoW folder ( and DO NOT!!! install any new addons etc. leave it all as it is ).
After this is done...
3: Delete your HB folder, download the "LATEST" new HB version ( if you had the latest one, redownload it ).
Instead of downloading files ( like CC etc. ), try to leave everything as it is. Only download your profile (.xml) file.
4: Be sure your WoW is 100% patched!
5: try to run your character now with HB.
FYI, my wow is running windowed ( and only did set up the video settings, no changes in interface ). Dont know if that matters anyway.
And i left the mesh folder unfilled ( as long this gives me no problems ) from HB.
Hope this will work out for some of you aswell.
