So this bug is one that is a major issue. When my character was level 10 I entered timewalking into DF content, and when I hit 61, I was booted out of the past and back into the present; or so I thought.
When I had invited a friend into my group it said I was phased into a difference instance, a timewalking instance. I went to talk to Chromie to fix the issue but there was no option to go back and fix it. I removed all my current quests, went to Stormwind and back to Valdraken, but nothing worked. I also put it a ticket and all I got was an automated response.
