Perhaps this can't be answered until the patch is finalized, but out of curiosity...
Lar mentioned that the path to hoseage is to have upgraded to (or started with) 1.4, saved a game under that version, then upgraded to 1.41 (and presumably saved game(s) under that version).
So, once 1.42 is out, if you are someone who did the above, is it recommended that you load in your last 1.4 (or earlier) save, and begin playing from there? Or, on the other hand, will it be safe to load in those screwy 1.41 saves that were upgraded from 1.4?
Also, you will need to perform the proper ritual sacrifice to make everything work.
