Thanks guys!
thins look pretty solid at this point. mP is still problematic but it's not a deep seated issue, just syncing issues.
Re the AI, they had made it so that it tries to build a shipyard first on a give. Planet which is non ideal. I've started to look into that code and made some improvements there.
also, re elemental, don't make me get the taser out. As a practical matter, having shipped a lot of games over the past 20. Years, beta 6 could have been the shipping game and we'd been fine. Elemental was a whole different case, something that wouldn't happen today since we would have just moved the date back a month or two.
