Discussion about the map editor for Heroes 5.

I have Heroes of Might and Magic 5, version 2.1. The editor is the original English version, also 2.1. As far as I can tell, I'm quite capable. But the Heroes editor surprised me with its clunkiness and inconvenience. I just can't seem to get along with it. For example, it's impossible to set a random Castle to appear after a certain time has passed since editing the map. Plus, there are some issues with moving these Castles; sometimes I have to manually change the coordinates of a "Castle" object. I could only create a Shipyard in one Castle; if I rotate it, the game immediately says that it's impossible to build a Shipyard in that Castle. Maybe I'm just not very bright, but it seems to me that the editor is overly complex. To do simple things "on the fly," I have to dig through various Manuals. In general, I'm interested in the opinions of people who actively build their own maps: how do you overcome all these problems? I decided to create a couple of ideas for Heroes here, but so far, nothing is working out. Maybe there are some good explanations of all these issues on the internet.
Thank you for your attention :) It turned out to be some kind of emotional outburst :)
