I've had that happen before, hadn't checked my stack bolts in like a year or two on my old commuter/beater.
Must have been riding with one missing for a while, once the second one worked loose, the chainring flopped over like soggy pancake while taking off from a stoplight.
Now, I do a 15 second check before I ride (wheels, chain, chainring, brakes) .
