setting frames_dir is not working?

Congratulations on the package!
I tried to configure the directory where the frames are saved during their creation and it didn't work.

Even though the folder I want to select is not within the temporary directory, I thought it was a better example to show that I can't make it work.

On the other hand, if I use "frames_spatial" and then "animate_frames" it correctly generates a gif file. But if I then run it again with a new dataframe that has less rows than the previous one, it creates a gif but using all the frames in the temporary folder. This way the second gif contains an animation with the frames of the second dataframe and then the ones of the first one.

Example: First dataframe from which 50 frames are created. Second dataframe from which 30 frames are created. The second gif has the correct 30 frames and then the last 20 from the first one that are still in the temporary folder where the frames are generated.

That's why I wanted to generate them in different folders since it's practical for me to have both the frames and the animated gif available.

Thanks in advance and again congratulations on the package created.
