my experience with the latest patch went something like
install patch for sins and entrenchment (it archiving both games before updating)
run game get notified i had to uninstall and reinstall before applying new patch (WTF?)
uninstall
un-archive latest created archive (the one it just created 20 min before) for SOASE. that seems to complete successfully, but entrenchment not so much.
try to play SOASE only.
mini-dump black screen of death upon launching SOASE (not entrenchment)
uninstall SOASE AGAIN
un-archive last known good archive for SOASE (1.1) F entrenchment for now.
SOASE launches fine
have impulse update SOASE from 1.1 to 1.2 (still no entrenchment installed)
have impulse re-download the 96meg expansion (entrenchment) and install (entrenchment refused to properly un-archive previous entrenchment archives)
create a new separate Entrenchment icon
Launch and play Entrenchment with with friends that have now been waiting over a 45 min to play.
Get 2 hrs in +- and mini-dump as usuall for us.
In short no change seen as a result of new Entrenchment Beta other than a BUNCH more headache. but thats SOP by now.
