Summary 0007342: ?/'ing 'M' ante causes invalid tile index assert
Description ASSERT(idx >= TILE_MAIN_MAX && idx < TILEP_PLAYER_MAX) in 'rltiles/' at line 9447 failed.

To reproduce type '?/mante'
My guess is that it is trying to render Anteus on top of something else, but that is just speculation

First of all it's Antaeus, not Anteus, and he has nothing to do with this bug. :p. Good guess though.

The search for "ante" was hitting on "antenna" in the description for MONS_SENSED (the dummy monster used to represent a monster that you have detected with demonspawn antenna but cannot see).

The commit message will explain the rest:
Fix a tiles crash by disallowing look up of unspawnable monsters.

The command /?m lets players look up monsters by name and description. Due
to an oversight, _find_description in sometimes returned the
dummy monster entries for sensed monsters (MONS_SENSED,
MONS_SENSED_FRIENDLY, etc.). When _find_description finds more than one
match, the matches are presented in a menu.

On console, this was strange but functional.

On tiles this resulted in a crash. The menu handling code in
expects that all monster tiles are stored in the texture (sprite sheet)
player.png. The tiles for the sensed monster dummies are actually stored
in main.png. When the menu attempted to draw itself, it would essentially
look for the tile in the wrong place and trip this assertion in
tile_player_info in rltiles/

Change: _find_description now filters out all M_CANT_SPAWN monsters from
the results. The monsters with M_CANT_SPAWN are: M_PROGRAM_BUG (which was
already being explicitly filtered), axed monsters who's data is being
preserved for save compatibility (which were being implicitly filtered
because they did not have descriptions), and base type monsters like

So I fixed the bug, but there is still some ugliness:

1. When you get an exact match, but you also get a bunch of partial matches, you are presented with the exact match first and are shown the menu only if you press space. The description's footer is supposed to be "?This entry is an exact match for 'FOO'. To see non-exact matches, press space.". If the monster has an extended description, then the footer is supposed to be "Press '!' or Right-click to toggle between the overview and the extended description.". On tiles both footers appear. On console only the second does.

2. The menu driving code in is responsible for knowing what texture(/sprite sheet) various tiles(/sprites) are stored in. EDIT: The menu code and the tiles code is really confusing and messy.

Yeah, I realised I had Misspelled Antaeus some time afterwards. Thanks!
