Hahaha. (Seems like the bloom filter library isn't set for maximum false positive rate and/or to autoexpand.)

Edit: Actually there's a BloomFalsePositive setting, maybe it never gets used? Also maybe it's not a library and it's a custom implementation.

I guess you've never made a silly mistake, found it, and admitted it.
