Hello, Barbara!
I purchased VV: TLC at Big Fish Games the 17 on February 2007. The exact version number that's displayed on the menu screen is 1.00.
It was on my 3rd tribe ("I Pappagalli"). The 08/23/2007, Mali found a vial that he drank and became Master Parent at 100% (and not doctor as I said, sorry). It's a few days later that I made my villagers drinking some stews for their health and that I notice something changing in their skills. Mali was also master scientist at 100% and his skills of parenting and research decreased at 90% (or 95%). Mali who was also master scientist at100% became master scientist at 90% too. I know there are others (they all ate theses stews) like that but I didn't note it. It's difficult to remember every thing that happened, it was more than 1 month ago!! Now this tribe is "complete", they are 115 and it runs almost alone! It's difficult to keep tracks of what they do (and I don't have enough time for the moment to follow them)
I may try to make again these stews, this week-end
