Hmm.
Just tried to start a new career game under .23. Either the base game is now broken as hell, or something in our mods is.
Parts tend to spontaneously shed their connections. Even the extremely basic Pod, fueltank, engine craft loses all connected parts when it's put on the launchpad.
Started a game in sandbox, and even the Squad crafts were falling apart on load. The airstrip was almost as bad. Loaded up the Aeris 4 (or whatnot) and while one engine fell off, the other two were apparently fine. Tried taking off... never moved. Brakes were off, jets at full throttle and throwing out lots of exhaust (>240 combined KN) but not budging an inch. Yet, somehow, I was hovering just above the ground. Color me completely lost I suppose.
In other news, I forgot to uncheck the keep updated box, so I'm now on .23, and can't be a part of the game until/unless we migrate to .23 as a whole.
Craft loading times (and in-flight lag) are a tad ridiculous. My basic rocket was loading as if it had 100 parts, and the decently sized rocket I tried first (not knowing crafts are FUBAR atm,) had maybe 60 parts, and loaded like it was approaching 300+.
Also, incase it hasn't been seen:

I'm not sure what actual mods we *have* to move with (as dictated by the in-flight craft) but I know we've got some very non-standard parts in orbit, so we can't bump back to plain vanilla without losing at least the communications network. (Unlocked parts may mean the whole save is basically invalid.. dunno.)
