I'm sure you'll make it back up. We all have things like this happen to us, for example my unusual that I had dropped from 4.5 buds (when buds were about 18 keys) to about 2.5, then @Vector brokered it for me and he got 1 bud profit from it and I got 1 bud too because we made a deal, so I lost out on a lot :C
But hey I still managed to get my dream unusual (Chiroptera Venenata Front Runner) that was worth 100+ keys in the end! ...until I sold it :>
