First off, good work on the lift, irrespective of whether it was more or less than last time around. 
Secondly: dude - if you Crossfit, you should never worry about 1RM.
I say this with an entirely straight face: Crossfit won't make you the strongest/anything-est person in the world, but it will make you a very good all-rounder... that, and most people will have a bias towards something (i.e. tall, skinnies to the cardio elements, short and thick to strength... before we even get to muscle types, training histories, physiology, etc. into account).
If you want to lift heavy, lift heavy: you won't do this regularly enough at Crossfit, or with the right preparation (i.e. taper, rest, food). It's like some guy being awesome at spinning in a gym, but not being able to cycle for toffee in a road race or whatever.
Even within specific sports, like weightlifting: lifters are (generally) good at the snatch or the clean'njerk - not both. It can happen occasionally (Liao Hui, Aramnau, Rezazadeh) but people are either quick (snatch - Rybakou ) or strong (clean'n'jerk - Ilya Ilin).
AND THEN... you have the sucky rises and falls that goes with any training, stuff that sets you back by X weeks/months. It happens and it's rubbish...
Key thing is to pick yourself up, traing better (not necessarily harder) and lift moar.
