super fast skill glitch

i don't know how i did it but somehow my sim was glitched and he learned skills really quickly. i have no mods on, the only other thing i may occasionally have on is testingcheats for motives.

my sim learned everything at a really fast pace. i got from painting skill lvl 1-10 from painting 1 picture. i still don't know how it happened but apparently it only works with skill items (easel,chest table,etc.) and books, doesn't work with things like cooking to gain skill or tinkering.

wish i knew what it was though lol.

Is your Sim related to a vampire? I know a half-vampire of mine used to learn skills in that speed.

yea.. my sim is a offspring of a vampire.

Look at his traits, there are a few traits such as fast learner that cause Sims to learn skills faster. If I remember right , vampire offspring get fast learner as their first trait, but it may be a different skill boost trait since its not working for the cooking skill.
