Heroes portal doesn't work correctly when used by underlords (?)
There is a map in steam workshop where you fight against usual underlord creatures by using hero gates. You are able to capture hero gates, and they spawn heroes for you depending on rooms you have.
So I feel like in such cases heroes portals work incorrectly. For example:
1) I got one singe bard after building a tavern. Why only one? Why tavern doesn't show how many bards it can attract? Was it actually tavern, or it's just a coincidence, and bards are spawned no matter what? There is no information about it.
2) Gates shows arcanists as available units after I built sanctuary and archive. Yet I still don't have a single one.
3) After building foundry the gates show vanguards and wardens as available. Yet I only get vanguards.
All other heroes spawned when you expect them to, ie Arena leads to huntresses. But looks like arcanists, wardens and highguards never spawn, even though gates show them as available units.
