Research Conservation on the computer no longer causes every skill the Sim knows to increase rapidly.
Fixed in Patch 1.54.120
I kinda have enjoyed this as it's given me skills in gardening and cooking, which makes sense to me as it's conservation. Perhaps not whole levels, as I've had, but it makes sense that researching conservation would bring up things like how to garden/cook sustainably. Though I've also had my video game level rise up. Worst I ever had this was leveling up 4 skills while I was researching conservation, and none of them were logic (though it was still leveling up).
I also have no mods or CC so this is a clean game.
Have also had this bug of random skills boosting up extremely fast just from researching conservation. Not just logic, but also video gaming and cooking - recently used skills as stated by others.
Going to have to avoid this career path until this bug is fixed, no matter how much I want to see where it leads.
At first, I though this was just a way of gaining skills related to the Conservationist career - since there are multiple applicable skills.
And then my Sim received the Video Gaming skill and an increase in his Cooking Skill. Hrmmmm?
