I get the following on MathHub/courses/AI/problems/csp/quiz/:

  32   A new \sn{semester} begins and you, as a \sn{student}, want to prepare your schedule by assiging

  34   Tuesday, Wednesday, Thursday, Friday).  You have 3 classes: Programming, Linear Algebra,
  35   and Artificial Intelligence.

  37   However, you do not like to attend a Linear Algebra class on Fridays or Mondays because
  38   you are usually not in the mood for math.  Additionally, you need to go work an 8 hour

Apparently, snify created

 \usemodule[smglom/education]{mod?lecture\usemodule[courses/FAU/AI/course]{csp/slides?csp-intro}

earlier.

[jfschaefer]

I've fixed it so that snify won't crash from this anymore and instead warn the user.
I'm not yet sure how to reproduce the wrongly created usemodule...
