Original AoM Tutorial Campaign

Discuss Original AoM Tutorial Campaign

Hello, I’ve been working on a custom campaign for 4 months now (your tutorial was very helpful, thanks a lot), but now that I’ve finished it I can’t publish it. On the site and in game I get an error message which doesn’t explain me why my mod can’t be published, do you have an idea of what’s going on by any chance ?
Here’s a screen of the error message

I’ve never seen that error before, so I’m not sure what could be causing it.

It looks like something that is account related, so maybe it’s something Steam/Microsoft account related. But I have seen some people post error messages that are unrelated to why it’s erroring. So potentially could be something with the files if you’re including anything non-standard.

Might be worth posting in the modding section of the Official Discord and maybe someone else knows.

I’ve finally found the source of the problem (the format of some of the images)
Thanks anyway, and many thanks for your mod which has helped me enormously!
