SP Computer Dominion Blitzkrieg question

[sansanjuan]

Edit: Sorry.. it was Arco who dominion swamped me and I was Bogarus. Sorry 'bout that. I modified the original body.

Perhaps a foolish question...

Last night I was playing SP as LA Bogarus and was slugging it out with Arco (at Mighty if that matters) on the frontier. We each had about ½ the medium map.I decided to turtle up and play with researching and casting some of the higher level spells. I was about six turns away from casting Utterdark (had a fair number of summoned undead, high level Death casters and buku death gem income). In the space of just a few turns my dominium flipped map-wide though I was building temples like a Mormon and preaching like a Southern Baptist (no offense intended to either). Any idea what befell me? Heretics? Is is possible to see what the computer had going on from the game files?
Tnx,
