FULL DISCLOSURE: Im using the console debug mod. Im on my 7th playthrough and ive always had a problem with making money so the past few playthroughs ive been using this (it may be relevant). Now to the problem: I did an early Gremist quest line, it gave me the rewards yet i cant buy from him as i should. The second bug is that i dont receive the Witcher Ursine Set Armor (havent tested others) buffs, the ones you get from equiping 3 or 6 of the same set. Im sad :(
