Interesting. Skript uses both Object#toString() and Debuggable#toString(Event, boolean). Skript's SimpleExpression helper class automatically overrides toString() to return toString(null, false), which is why most other expressions work completely fine.

I have a few other classes that extend Expression instead of SimpleExpression, so it looks like I'll need to update those as well.
