What happened:
Subbed character is teaching a class to 2 F2P characters. One F2P logs out listening to one class, then later logs back in after the skill being taught has changed. They try to listen to the new class, but they're told they're already listening and need to STOP listening first. So they stop listening. This causes the subbed character's class to end, apparently. So they switch to a new skill and try to teach both F2Ps again. This is what the subbed character sees.
