Short description of error
Exact steps for others to reproduce the error
It was working normally before. I keyframed the shape keys, and another property on the modifiers.
Then i duplicated the object and was trying to offset the animation of the new object, but as i didn't know how, i started to try a lot of things.
When i noted, i could'd work with the keyframes anymore..
And it happened to me so many times on many occasions, not only on shape keys. Other properties too.. Suddenly it just stops working, after a time working on it.
i don't know what could have triggered it.. i have no idea how to replicate.. And my file probally wouldn't be of help because i worked make things on it, but i will send it anyway:
