I've patched the house navigation system to restore most of the downstairs doors to go to their original locations - the only change is now that the door to the garage is nonfunctional and you need to click on the large carpet instead. Apparently JamLiz had received complaints that the garage entrance was hard to find for new players, so he re-tooled the navigation for the downstairs area - this likely made it easier for the new guys, but it confused the fuck out of the old dogs like me.
Drop this file into the \SexNote-0.074-pc\game\code directory (this directory likely does not exist - you'll need to make the \code subdirectory), and make sure to strip the numbers off the front end of the filename - it should just be "navigation.rpy". You may get a crash on the first run of the game after installation of the mod - this is normal in the current versions of Ren'Py, and you can just close and re-launch the game to continue on.
This file is not created or endorsed by JamLiz (although I've told him I made it) - using it shouldn't cause any problems with new games or old saves, but you'll still be running a modded version and JamLiz might not be willing to help with any crashes you may experience (although those shouldn't be related to this mod - I played all of the new content with this mod's changes in place).
