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
ACME, fortunately, is up to date:
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.
For PoB my wallet should be online. But after transaction to burn address my wallet always crushes. When wallet is empty - it's ok. After wallet.dat is changed or importprivkey command, wallet immedeatly crushes.
If -rescan flag isn't used, wallet doesn't crush, but burn information is lost.
