Blue crystal disappearing

Could someone please look into my account, Playing on world 63 and my blue crystal stash keeps disappearing.  No I'm not spending it. I had 444k last night, I clicked repair all which was valued at 37k. My total went down to 115k. Go figure. Then later on in my main base I was upgrading my defenses with nearly 300k of blue crystal then whammo it showed 232.Not k. I was out and I had only upgraded one missile squad to lvl9 Hmmm. It slow going without this.  Thx in advance
