Next, a list of all possible bugs in the standard map editor and templates will be provided.

Unfortunately, the standard map editor has serious shortcomings that could not be resolved with its functionality; whether these are bugs or not is up to you to decide.
It was precisely this that led to the creation of IRMG several years ago. I think you understand that if everything could be solved within the standard map editor, no one would have spent so much time writing their own generator.

However, for a beginner level of skill, the built-in map editor is more than sufficient.
You can ask Moza for a detailed list of bugs that led to the creation of IRMG, if he wants to remember it.
