Ok, now that is just plain wrong. I am playtesting the latest version now. Klint wears armor (and if he is in the lower-grade armors, he will level up) and the game loads just fine. However, even with the last version (2.0), there were no problems with his armor and saving games. I have never experienced these other bugs. As for that door in the rat caves, just did that part of the game yesterday. No problems. I suggest you go back and reinstall the game from the beginning following the installation notes and making sure you follow some of the other advice people have found when installing this. I say this because most problems people have with seemingly random crashes and not being able to save/load games is usually due to problems with .pro files.
