Please help: Cheat detection problem

[Dogboy]

I just fired up a new game with my son and two friends. The first turn, I get an error message for 3 of the races:

"[race] has cheated
[race] has a God that is too powerful considering current Dominions 3 rules. This might be caused by cheating or by using the wrong mod when designing the God. The offending God has been reduced in power. "

My (non-dormant/non-imprisoned) pretender is absent.

What could cause this? I know that no one is cheating. I believe everyone is using the 3.21 patched version. (I know I am, and my race was one of the "cheaters").

We are using the Arduria map, modified for Dom 3. Could that be a problem?

Any advice would be appreciated. I'm leaving for a week on Friday, and would dearly like to get the auto host set up before I depart.

Thanks!
