I ask because I had to delete my .myw file as one of my quests got bugged and when I reinstated the file, all of my quests that I had already done flooded the screen with there completion text and I never noticed how many skill points I had prior (nor did I notice my xp as I only thought about this conundrum a few days after the event - I was just pleased at the time that I fixed my broken quest which took me all day).

I had a similar problem with Giesel quest. I don't want the stupid sheep to die. Do you know of a way to reset just that one quest?

I have tried the Test2 and I can confirm it now displays the Atlantis items correctly, though I can't confirm the same for the EE items as I have no characters in Legendary difficulty and the same can be said about the new mastery because I also have no new character with the new mastery currently.

Note that before you replace your files in the TQvault folder, don't forget backup your vaults too, just in case it hits the fan.
Your vaults should be located at C:\Users\username\Documents\My Games\Titan Quest, where "username" is your computer user name

Cheers
