No-go areas disappear (when saving new ones)

Expected behavior
When I create no-go areas in my custom map, I expect them to persist, also over multiple editing sessions.

Actual behavior
When I create a no-go area, all so-far existing no-go areas vanish when saving the map.

Steps to reproduce the behavior
1. Edit my custom map (https://atwar-game.com/map/?id=24387), add new no-go areas.
2. Save changes
3. Revisit map (play, preview, or edit it)
4. All previously no-go areas gone (again).

Any other relevant information: The map was completed and working perfectly well. Some random day, about 100 days ago (according to my game history), I realized that all no-go areas were gone, suddenly.
Redrawing is not working, as explained above. I spent afternoons redrawing all the no-go areas, just to have the other 50% from the previous day be gone the next.
It's inexplicably frustrating, when one completes such a huge map/project and see it work all well, just to suddenly have it been broken.
I plea: Reset my map to a long time ago, when all no-go areas were still there (like 900 days ago, I believe). I am sick of drawing all borders for such a huge map a 4th time.

Redraw 1/2 - a couple of weeks ago


Redraw 2/2 - a couple of days ago (now all areas from 1/2 are gone)

Same thing have happened to all the maps I have updated recently. Each new save seems to delete every no-go zone from a previous one.
I hope it can be fixed quickly, as it breaks a lot of maps.

Dave, any update on this? Can the team revert the map back any time soon?

Up

Can anyone reset this map to a working state please?

Up, still broken

Is there any fix for this in sight?
Or can I get any update on a reset of the map?
Apparently my other Alagaesia Map is also affected...

This has been a thing for years and I have constantly told Dave to fix it. I've even tried getting admins to turn my map back a few saves. None of them has helped, leading me to quit atWar a few years ago. Don't expect it to be fixed anytime soon.

If Dave sold the game, I'd have it fixed in no time.

Time to sell up.

Bump. Anything you could do Sascha?

unfortunately not...

Saw in another thread that someone's map was reset to an earlier safe. Would this be possible with my Battle for Hoenn map now? Pretty please?
