Problem with AI going AWOL

[Maddog]

Ok, keep in mind I'm a n00b here, and not very computer literate.
I played RA years ago when my son started playing so we could both do something in common. I picked it up again just recently to pass the time.

Here's my problem: When I set up to play a single player skirmish, I have no AI opponent. How do I get him back? I've searched the setup window, clicked nearly everything, but can't find where the AI option is located.
I am sure there is an easy answer, but I'm not seeing it (refer to first sentence, par. 1). Since I just started playing again, and am "re-learning" a lot of this, please be patient.

Thank you in advance!

I'm assuming you mean OpenRA here, since you also emailed me about this.

Certain maps (such as those with disjoint islands) disable bots because they would otherwise cause significant performance issues.

If you select a different map the bots should come back!

Ah, ok. That makes sense. Will attempt again, and report back.
And, I apologize for the multiple communications.
