After collecting the 6 shimmerweeds, I attempted to zone back to the starting map and the game began immediately playing the opening cutscene to the bonus campaign. I had no items, rokhan was gone, and chen was back in his inital quest spot. The campaign literally restarts itself. reinstalling or loading older saves didn’t fix this issue. I opened a ticket but apparently this is the only place to maybe get an answer. If anyone has any suggestions or any ideas what might be causing this, any help would be appreciated. From what im seeing, there appears to be a litany of bugs regarding this campaign in particular. Not sure if this helps, but im playing on classic graphics since it performs much better for me and playing on the most recent patch.
Do you get this bug in HD?
I just tried it while dropping the graphics and the same thing occurred. something else I forgot to mention is when I had saved my game in the thunder lizard zone, a folder appeared with the same name and then every time I would try to save again new folder names would appear. very weird and has only happened in the bonus campaign. not sure if im allowed to post screenshots but I have one that would show what I mean
Others have (had) the same/similar problem as you, check out if my reply can help.
