It seems that this doesn't happen in the campaign – stables and wells are always limited to one. In new and recently edited old templates, duplication occurs quite often. It remains to be assumed that modern template creators are "to blame."



It seems that no one doubts anymore that everything is tied to the ratio of the value of the protected objects and the protecting monsters. You can see the values here: http://dreamcatcher.metroland.ru/templates/index.html
The problem is that, in addition to the actual ratio of values, coefficients (which Vic, I think, calculated) must also be applied to calculate the number of monsters, and the result is quite variable. In my opinion, it is more convenient to gain personal experience and use it.
