The readme's are updated with every new release, but since the mod is still in beta new bugs can be discovered and/or fixed every day. For that reason you'll want to read the MedMod thread as well, at least the posts made by Wes. You may want to keep an eye on posts of SLIC-coders (mainly Dale, Gedrin and me) as well, as many bugs are SLIC-related, but those are less important than Wes's.
The savegame bug you mention was fixed a long time ago, but we did discover a new one recently (don't you just love this game?

), which will be fixed (or rather, worked around) in the next update, which should come sometime this week. More info about the bug can be found in one of my posts in the thread (only posted two or three times in the entire thread so shouldn't be hard to find).
