The mod's name and its ID are the same (except there are no spaces in the latter). Try looking through mods that start with the letter "R", or see if it appears at the bottom of the list. If it still doesn't show up, then the mod should load after you resubscribe and restart the game.

It kinda sucks that we'd have to wait until Build 42 comes out which adds a better Workshop mod menu where you could search for specific mods or enable/disable them all at once.
