Upgraded from 2.63 -> 2.6.10 -> 2.7.7+
This issue first popped up in the 2.6.3 to 2.6.10 update and I was hoping a move to 2.7.7 would fix it when it updated the database. I cannot "update assignments either" from the 2.2 module. I let MySQL (5.6.15) repair the tables before I performed the upgrade to 2.6.10 and it didn't find anything wrong. Whenever I try to add an assignment of any type (quiz in this case) I get errors like this:

Invalid course module ID
More information about this error
Debug info: SELECT id,course FROM

WHERE id = ?
[array (
0 => 3353,
)]
Error code: invalidcoursemodule

line 268 of /course/modedit.php: call to add_moduleinfo()

Also I can't backup courses, I can't do ANYTHING. I initially tried to update assignments from the old 2.2 assignment module and get a big fat error like this:

Can not find data record in database table assign.
Debug info: SELECT * FROM

WHERE id = ?

0 => 3,

Upgrade assignment: Vocabulary week 1 (Course: Demo Course)
The assignment conversion was not successful. The log from the upgrade was:
[[couldnotcreatenewcoursemodule]]

The last record id in my mdl_course_modules table is 3361 and every time I attempt to add the assignment or quit that WHERE id = ?
[array (
0 => 3364,
)]
[array (
0 => 3365,
)]

It increments by one with each attempt, why is it pulling record that don't exist. Is there a bug in which the record isn't being created in the first place?

It seems like add_moduleinfo() in module_generator.php is failing to add the course info from /course/modedit.php. Not sure why.
$cm->id = $DB->insert_record('course_modules', $cm);
course_add_cm_to_section($courseid, $cm->id, $sectionnum);
return $cm->id;
