### Homework set editor bug? (can't view problems in 2.4)

I will try to submit this to bugzilla but perhaps it isn't a bug. When I add problems to a set and then click on homework sets editor and then click on the problems to edit the set I get a webwork error. This only seems to occur if the problems have not been assigned to me, if they set has been assigned to me then there is no error.

Here's the error message:

### Error messages

Can't call method "assignment_type" on an undefined value at /opt/webwork/webwork2/lib/WeBWorK/ContentGenerator/Instructor/ProblemSetDetail.pm line 1748.

Hi Blake,

This is an annoying bug in version 2.4 where viewing problems fails when the set isn't assigned to the user. If you assign the set to yourself I think it resolves the problem. Or, check out version 2.4.1, where I think the bug is fixed.
