I'm encountering a little issue :
=> When I export my theme then edit it and then import it back the CSS modifications do not apply in the Experience Editor (event after opening the editor again, iisreset etc...)
=> But when I publish my website the correct CSS is applied
I checked if there was multiple versions of the Stylesheet in the media library but that's not the case.
It seem that the Experience Editor keeps showing the first version of the theme I imported back and when I use the Export feature it generates a corrupt CSS file containing the following HTML lines at the end :
But it seems to be the lastest version of the problematic CSS file.
I'm using Sitecore 8.2 rev. 160729 and Sitecore Experience Accelerator 1.1 rev. 161004 for 8.2.
