Client libraries not getting picked up after upgrade to 6.3.2

[joe_s66]

I'm upgrading from 6.2 to 6.3.2 (fresh install) and the custom client libraries are getting built but not picked up. If I replace the following tag in headlibs.html with a hard-coded link to the style sheet, everything works. For some reason the clientlibs isn't loading correctly in 6.3.2.

REPLACED THIS:
<sly data-sly-call="${clientLib.css @ categories=['atmfs.vendor','atmfs.site-all']}" data-sly-unwrap />

WITH THIS:
<link rel="stylesheet" type="text/css" href="https://forums.adobe.com/etc/designs/mfs-intranet/atmfs/site/all.css">

Sometimes you need to clear the var/clientlibs/<something> folder. did you check this?

Also, try to invalidate the client Lib in dispatcher.
