Could not burn CAT shitcoins

[korolevsv]

1. Selected CAT as a fuel, pressed UNLOCK button
2. Confirmed "Approve" transaction.
3. Tried to burn 3580 CATs.
4. Can not see any result ("Your balance is: 0 Pyro")
   PS Maybe step 2 or 3 was repeated twice: I can see 3 successful transactions from my account to BitClave contract - see https://etherscan.io/address/0x085e597ee982c2b4fbeb086de4dc01ddb7b67974)
   PPS I also unlocked TNS shitcoin, but can see only 1 transaction to the contract 0xb0280743b44bF7db4B6bE482b2Ba7b75E5dA096C (I suppose it is yours) prior to transactions to BitClave contract

5. Transaction error alert discovered when tried to burn TNS - screenshot attached.
   See also failed transaction https://etherscan.io/tx/0x810e2001f38a50c813963c3b78a7644d376487959518618be204332eab528b38.
   PS BTW TxFee of the failed transaction is 2 orders higher then fee of any successful transaction :-(
