The newest version of my mod "Sword Coast Stratagems", version 25, is now out and ought to be a bit improvement on previous versions for BG:EE in terms of stability and ease of install. It should be compatible with version 1.2 of BG:EE and (with any luck) with BG2:EE when it comes out later this week. The new version fixes a host of bugs large and small (though mostly not with BG:EE, as it happens) and (with some trepidation) I'm declaring it non-beta, though realistically it's still beta for BG2:EE.
Edit: after two fast updates in response to problems identified with BG2:EE installs, we're now on v27. I've had to disable the "Improved Vampires" component on BG2:EE installs for the moment: some kind of animation bug is causing crashes and I don't immediately have time to sort it out. (If you have installed that component, I recommend uninstalling it.)
Edit: version 29 now out. Many thanks for Mad Mate and others for the unofficial Fixpack they produced last year; fixes from that are now incorporated into v29.
