Method Error with atframe

[MAminSFV]

I was trying to visualize the ODE solution after simulation was done, and I got an error from the 'atframe()' function.
I am not sure why but the error is about the argument 'frame'. I checked the var types and the package .jl code but could not find the root of the problem.

I had the same problem with the quickstart example, so I think it is independent of the mechanism inputs.
Can it be a dependency problem?

Thank you for your amazing work and contributions @tkoolen @rdeits.
