So I’ve recently tried to make a terrain flag that affect sight ranges of player and other creature. It works for player : when you step on terrain with the flag your sight is reduced to 1 tile, but when I spawn a monster on the tile and stand more than 1 tile away I still get a `!` next to the monster name in the the `V` menu.

I’ve edited `Creature::sees( const tripoint &t, bool is_player )` , and `monster::sight_range( const int light_level )` . And here’s the [PR](https://github.com/CleverRaven/Cataclysm-DDA/pull/27719)  
So my question is : what did I miss about creature sight ?

After some more testing it turns out that it works. Spawning the monster directly on the tile was the mistake as monsters spawned on the tile don’t get the effect.
