While working with other parts of the The Burning Blue Module I noticed that one of the maps (German Raids) is now blank. It is multi-zoned, and when I look at the zones, I can still see the map image using the Define Zone button.
I have tried to change the map image from png to jpg, and I have tried loading another map, but it still is blank.
There is no relevant message in the error log (Well, actually there is a frustrating “Error in expression” for the main map, but no more details, even though the audit trail is switched)
I have also tried to remove all the zones for the map, but it remains blank.
Some time ago, I had the same problem, but at that time, it was solved by deleting the image, saving, removing it from the vmod file, and reimporting it. This time I have not been that lucky.
An obvious solution would be to remove the map entirely, and rebuild it from the ground up, but there are lot of zones, and I am loath about redoing all that work.
