Hm. I'm definitely solo'd due to retreats (
gameID=151389), I don't recall a game I've played where someone has been given a solo even though they had an empty SC where someone was about to retreat to; do you have an example of that? Anyone else chime in?
To summarize:
1) Checking for solo win should be made at and only at after Fall build phase a la boardgame/official rules
2) According to my experience, this is correct in that there is a solo-check after retreats
3) But not mutually exclusive to webDip checking for a solo after retreats is that according to thomas, webdip may be making a solo-check before retreats in the fall phase [as well]. (would this be fair to say thomas?)
