Beast den tooltip does not tell you if it's too small to attract beasts.
Odd. It usually does for me. Is this in single player or multiplayer? The general idea is that so long as you have a 3x3 beast den, any subsequent squares count towards attracting beasts.
Edit: Just checked and can confirm. The tooltip exists in multiplayer but not in singleplayer.
Confirmed as well, see Webernever1's replication on Userecho. Passing through to code team.
