I would like to know is it possible that hash of transaction will change during chain reorganization?
I noticed that difference is only between block number and block hash.
Also, polling geth with eth_getFilterChanges sometimes can deliver even number of reorganized (removed) transactions and regular one's with same hash, which means that transaction is not mined at all, but if i check that transaction through ropsten.io - it is fine. Is it bug of geth or something else?
