Your selected settings don't match the template's capabilities, which is why a random map is generated. To avoid this, you need to know the parameters for each template – size, difficulty, number of players. Look around the website; there's information about the templates there (I even found answers to my questions in this thread).

Is there any information about the possible settings for the templates, or is there a way to get it from the template itself?
I would implement it in HD so that when you select a template, any unsupported settings are automatically disabled.
I haven't been able to figure out which settings are supported for some templates, even though I've tried everything, and the map won't generate.

Here's a question. Is it possible to make it so that,

if I have the bug-fixing function enabled, and my opponent is playing a clean SOD (Save-Or-Die) and can see my income and the troops in my garrison.

Can I completely block access to this information? Or, at the very least, send incorrect information, like 4000 income and 100 archangels in the city every turn :D

I don't really want to enable it because of this.

In the HD 3 betas, map healing and gameplay bug fixes are already separate, but both are linked to the Tournament module.
Beta 10 is coming soon, and it will be great. I think there are only a couple of betas left before the final release...

I won't try to implement the ability to send false information to the opponent in SOD; it's probably too complicated and could be a potential source of new bugs.
