Can't update asset store package

Hello

I’m having an issue when trying to update and reimport a package bought from the asset store. When I go to my assets, I have clicked on update, then on reimport in my project, unity does seem to reimport but the new content of the package, which can be seen in “Package content” on the asset store page of the asset, is still missing as if it didn’t get updated. I’ve tried deleting the package in the folder where unity downloads asset store stuff, and then download it again, but i still don’t have the new assets in this package, even when importing it in a brand new project…

If anyone can help me… Thank you!
I’m on 2017.2.0f3 by the way…

I’m on 2017.4, Still cannot update the package just by clicking update on the asset store, but now if I delete the package kept originally in AppData/… folder, i can download again and get the updated version it seems.

Maybe I should mention that I have moved the folder where asset store packages are downloaded to an external hard drive, through a symbolic link…

Do you think it’s a bug? Or a consequence of the use of symbolic links?
