Is https://bchain.info/SLM/ correct? I don't see my transaction from exchange and burning transaction here. Wallet crushes after burning. I think, that i lose my funds 
Can someone confirm that txid: 6242764151ebcace4589b88371007bb8411822f7d11ffae028738919d4253f1b and burn txid: d86b261b82e46810a82f85bde69b77e2a93d363ace761d8856d17d3d13c5e6f6

6242764151ebcace4589b88371007bb8411822f7d11ffae028738919d4253f1b shows up correctly, the burn transaction too.
Anyway, if a burn transaction (or any other transaction you do) "gets lost" (e.g. because it's included in orphan blocks) then you simply can do a "slimcoin-qt -rescan" (or "slimcoind -rescan") and the balance will get added to your wallet again.
The only way a transaction can get really "lost" is if it comes from an exchange (or online wallet), "gets lost" in an orphan block/chain, and the owners refuse to credit your correctly - but then they're scamming you, because in this case the transaction simply didn't happen.
