Premiere wont find folders

hey, Im workng on a project that combines camera footage and stopmotion animation,

all my animated material is saved as jpegs and raw files (single frames) on the folder created while creating it on DragonFrame, it's a folder that can be opened simply through file explorer but it also operates as the project file for DragonFrame.

I had no problem with it untill last week and now suddenly premiere can't find those folders,when I look for them at the source browser I find all the files in the folder containing the animation folders except for the folders themselves.

 is it an update that causes it?

is there any other way than copieng the jpeg to a different folder? thats a lot of files and I dont want to double its weight on my drive.

it happend to me through different computers, both my Acer laptop and the Pc at film school.
