Hello and i hope you are doing well. :)
I encountered this problem ever since the cross realm updates has taken place. My character is unable to mount in BGs and in arenas. In addition, whenever I'm in a raid the raid profile cannot be seen. i.e- i cannot see the name plates of my team. This applies for raids/dungeons/arenas/BGs. Its quite upsetting and i know the problem will be resolved soon. Months ago i had encountered another bug and it's present on the character till date. Whenever i change my spec from primary -> secondary or vice versa, my health drops significantly. I have to relog everytime i change my spec so that my health will go back to normal. I have tried repairing this toon multiple times but it doesn't seem to work. I do hope you take the time off to look into the matter.
