UPDATE: Morroblivion Unofficial Patch 2017-Nov-22 has been released. This version includes nearly all of the bugfixes posted below. However, you will need to start a new game, so the fixes here will still be useful for people who want to use their old saved games.
Looking for the Latest Bug Fixes? They are attached to the second post.

Since Morroblivion has been in development for many years, it's hard to keep track of which bugs have been fixed, still open or no longer relevant. Since I don't have the experience or resources to set up a bug tracking server, I'll try to maintain a list of active bugs for 2017 in this first post and a list of all fixed bugs in a second post. Feel free to post bugs and fixes you find in 2017 to this thread.
