Exploration achievements bugged and not flagging progress due to an old issue

Question

So I'm pretty sure this problem is specific to me and will be hard to reproduce now that the issue that caused it has been fixed, but I'm hoping someone will be able to help me out.

The problem I'm having is the same as in the first link, and sort of related to the 2nd. Basically as far as I can tell, there was a bug that was causing parts of the map that my characters had not visited, to wrongly show as discovered. When I do visit these areas for the first time, they do not reward XP, nor do they give progress towards the Explore "X" achievements, permanently stopping me from getting them without the use of gm commands. This bug only occurred in zones that I had visited at least once and on relog, the wrongly "discovered" bug occurred.

Is there a way for me to reset the map so I can get my exploration achievements without cheating? It's like this on all of my characters, in all of the zones I didn't fully explore in one session. I don't mind if I have to re-discover whole areas again if it fixes the broken parts.

In-game screenshots attached. I'm in Thunder Axe Fortress, but no matter what I do it won't check as completed. https://ibb.co/7G3fG7Z https://ibb.co/DbvRHyf
