after upgrading slugs were gone

I noticed this today which is very aggravating.

I set forum slugs when I upgraded to vB4 and vbseo 3.5 beta2

After that I always updated to the latest version never bothered to check all settings again.

Today when searching for image paths I noticed that my forum slugs were gone which means all urls for my specific forums are wrong now and have to be indexed again.

Please check that

Due to change on vBSEO 3.5.0 , some settings are not imported within datastore as the storage method has changed. That's why backing up and restoring backup is a mandotory step on vBSEO 3.3.x upgrade to vBSEO 3.5.0

I saved all settings and restored them after upgrade.
That is what I always do.
The issue however arrised not upgrading from 3.3. to 3.5.
it droped the slugs when upgrading from 3.5. beta2 (or 3) to 3.5. gold

I just did test upgrades on 5 different test site with slugs enabled and all are upgraded without a problem even without importing the settings ( 3.5.x to 3.5.0 Gold )
