The sprite used for the Thousandth Degree projectile was the Thousandth Degree itself, not the accompanying wheel. I noticed this behaviour when testing the weapon itself and saw that there's an issue for it: #745
I replaced ThousandthDegreeProjectile usages in ThousandthDegreeProjectileFired with ThousandthDegreeProjectileFired. See changed files and commits for details.
