I have tested this and sometimes have received the "TEMPORARY scope is unavailable" message when logged on from an extended period of time (see article below), BtBb article #: 000041501.
I am including Noelle Stephens on this...does anyone know if a fix might be included in CU1 for Q4 2015 or separate patch?
There have been some postings on the listerv and I can see where this will be confusing for students staying logged on to get this message with no log out option.

Service Pack: SaaS, Learn 9.1 Q4 2015 (9.1.201510.1171621)
Issue Description: Users receive a 'TEMPORARY scope is unavailable' message when their session has timed out. They should instead be redirected to the login page.
Steps to Replicate:
Log in to Blackboard Learn as any user and idle on any page
Wait until session has expired (Confirm via Authentication logs)
Navigate to new tab as user
The following error occurs:
TEMPORARY scope is unavailable.
When a user's session times out, they are redirected to the login page.
