These are all the things I could remember. I haven't had a chance to play the singleplayer yet, but I will report back in this thread if I see the first issue repeated, or the issue with the saves.
Update: After having played singleplayer for several hours, I can confirm that these issues are indeed specific to multiplayer. Weapon animations worked as intended and saves loaded properly and were stored without problems. I had no repeats of the problems listed above.
