As for mp - they did not add reg file into rars, so you will need to get that editor and make file yourself. I did not bother, honestly no one from here is gonna play it for few months i guess. And when i get new pc - i will not, too
As for sp - you can transfer chars from previous version (december 2018 something?) - they still work, some items might go missing since changes, but overall - my naked barb was working np.
