[Beta 6] Exit's highlight area for allies reveals hidden doors.

[Valguris]

See the screenshot -- hidden door was there indeed.

Ah, not a hidden door but a phase wall. Never checked for those, kinda funny!

(I tried to be really lenient with that area highlight, rather than use your FOV, because it can otherwise be harder to tell which allies might follow who are around a known corner, but that leads to lots of other issues and occasional/rare oddities in what is highlighted. This is the second such thing found only recently...)

it can otherwise be harder to tell which allies might follow who are around a known corner,

Maybe highlight all tiles in range except for the known walls (or, rather, floors and undiscovered terrain)?
I am actually not sure how the game handles allies behind a wall in this case.

PS. In this case it was a hidden door, not a phase wall.

[Kyzrati]

Oh yeah, I forgot there can actually be hidden doors in garrisons, too, since most are phase walls

Any highlighted space will transfer allies, that's why the display is so permissive. If not highlighted, no transfer.

Ha, just spent a little while wondering why I couldn't repeat this behavior for either hidden doors or phase walls, then after doing a comparison of Beta 6 code with the current base found that the fix for a separate ally transfer highlight bug reported earlier by DDarkray had already by extension fixed this one, too xD
