Not sure the tracker items linked and followed are the same thing.
This sort of thing requires some sluething, me thinks ... soooooooo ...
IF one were to inspect the questions.xml file in the failed directory (that long one in your error
9003b2869d9194ccf31ac22c4aa8e3d3)
will see a contextinstanceid tag. Like (example):
<contextinstanceid>94</contextinstanceid>
There needs to be a corresponding directory in activities:
quiz_94 (as per example)
That directory is missing in your issue ... quiz_7290.
Search questions.xml for 7290 to see if there is an entry.
To find the question in the course:
questions.xml will have a name tag
Example:
<name>Google Applications Quiz</name>
Go to the course and check out that quiz.
Might also run a health check (development/not supported) ...
As admin level user via
http://site/admin/tool/health/
It might report issues with quizzes and offer suggestions as to how to fix
(via sql queries).
