Describe the bug / Repro steps
Went into dialchat as a user with sysop privileges. Typed /color. Hit enter. Got to a screen where CYAN was highlighted by the cursor (fwiw, this kind of screen currently having problems for me via iterm, I havent gotten a better client yet, but same kind of screen as when creating a character in MMUD, I cannot progress). Anyway, I hit enter on CYAN, and ithe board crashed iwth the following error.

Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object.

Expected behavior
I'm not exactly sure, other than not crash :) Change my text to cyan I'd imagine.
