During the Life Coach request, no "special offer" option is appearing when trying to set up shop. Playing 64-bit v0.13.; still in Chapter 1; journal says "[Life Coach] Sell potions at the market and select Carol as a "special offer."" Have found no way to progress quest.
Also, have encountered frequent bugs with selling potions, wherein sold potions weren't properly deducted from inventory -- most of the time, unsold ones would just be lost to the aether, but occasionally fewer-than-were-actually-sold would be deducted (including having one of an item and yet keeping it after selling it). Keeping the potions-for-sale to a small number (~3) tended to avoid this issue. Really bizarre.
