The output of Byzantine Golden Horn Tower is only increased if the cistern is put to Conscriptio

Just tested it in game.

A batch of longbows takes 150 seconds if the cistern nearby isn’t put to Conscriptio even at level 5. After switching the cistern to Conscriptio it got reduced to 75 seconds.

If this is intended, the landmark description should be more clear, since it sounds like cistern would increase the output regardless of choice of cistern bonus.

It says that it increases the quality of the units it produces, not the speed, what u are describing is normal building behaviour, and im pretty sure anyone got it, so maybe u should read it again
