Bots Disappearing Issues

[Draugr]

Can anyone help me with this issue.

This only happens with one of my characters. My other character doesn't have this problem, neither does my friend's characters.

When I summon my bots, add them to the group, then zone into another area, all my bots are gone and I must spawn them then group them again. Any buffs on them are where they were in the previous zone, but this is strange that it only happens to my 1 character and not the other or that of my friends.

Anyone, have any clues?

Thanks,
John
