Gaps in map memory

[chaoticidealism]

When exploring, sometimes there are gaps in what the character remembers on the map. I don't mean that they eventually forget it; I mean that they never remember it to begin with. See attached file for an example.

Steps To Reproduce

Start a game, explore some, and notice that there are places that can't be remembered. This is especially noticeable in large structures, but will happen in one-tile houses too.

Expected behavior

Map memory shouldn't have gaps.

Screenshots

This is a mine level, fully explored except for the spot behind the poison gas. The stairs are off to the left side of the screen; the character entered through those stairs and explored the level. There is a memory gap right next to the stairs, and two more square gaps above the character.

I was able to fix the map memory temporarily by quitting out and back in

Good to know, at least there's a temporary fix.

Based on the symptoms it's something to do with the top level map memory cache. A tile is only eligible to be memorized the first time you see it, and it's ignored after that, so if you can somehow see a tile but it doesn't draw a memorize-able symbol, it will record nothing.

So maybe the best way to track this one down is to see when the "see a tile" function is called, and then figure out which instances of it don't come with a "memorize tile" afterward?
