This along with every other bug I am about to post (found while testing Sarpadia) has been duplicated in a test quest I made. Click here to download it.
On a BS-Overworld DMap if both the "View Overworld Map by pressing 'Map'" and "... but only show screens in this DMap" flags are checked the only screens that will appear are those checked off in the DMap grid.
EDIT: Here's a screenshot...
That's what the "...but only show screens in this DMap" flag does. "In this DMap" means "is selected on the grid".
For what it's worth, you're 'supposed' to use it for dungeons and interiors only.
OK, no problem. A layman's reading of that DMap rule suggested it would show all screens on that DMap, but nothing else. Check the screenshot below for what happens when that rule is unchecked.
Is there any way to prevent this other than marking all the screens on the BS-Overworld DMap (highly undesirable) or moving the cave on the right to another map (OK for future quests, but I'm not going to waste time doing it in Sarpadia)?
'Not A Bug' thread moved from quarantined to exterminated. Dark Nation (or other developer), how am I doing? Reply only in one of the threads I moved.
