Actually, I wasn't having that many problems using windows 64bit version in 0.24.2, considering this game is still in the making. In fact, the only problem recently I'd have is being able to load my ships from the tracking station (which seemed to be connected to MechJeb in some way). Otherwise, everything was pretty peachy. Is 0.25 that bad? The two huge, crash inducing problems I had with mods were (1) Final Frontier - because it seemed to mess up the save files, especially when going back to the space center if the flight wasn't finished (nice mod, but not working for me) and (2) having everybody and his sister using different versions of ModuleManager. This last problem seemed to get better after the updating frenzy subsided. Since all you modders seem to be unionized now, it would be nice if there were some standardization when it came to some things - especially the tweaking business, which has always bothered me. But it really seems like there ought to be some rules about ModuleManager to make it more predictable - keep it at one source and not in every mod file. Seeing how you all are communicating so well, that shouldn't be hard. RealChute is a favorite mod, but I am saddened that 64bit is not working out for it. I do hope it is revisited in the future.
