Account number must be 1 or higher to send transactions.
Account number 0 is unable to send transactions as identified in this issue.

This was happening here #217. Is happening again. To replicate, try importing an account and then changing the password (underlyingly changing the sequence and the signature).

Confirming, same issue in several places, for example:
This might be related to sequence number,
Currently have issue with creation of Osmosis pool:

1. Blank new account receive asset X and Osmo in Osmosis mainnet
2. Pool creation leads to the following error:
   You have too many concurrent txs going on! Try resending after your prior tx lands on chain. (We couldn't send the tx with sequence number 0)

Osmosis withdraw/deposit of asset is working.

Also noticed that in account that is "old" sequence in tx is "-1", when it should be "8", its "7", and with same error.

This issue has been resolved. Signature errors can occur for several reasons. If it's a specific chain issue, don't make an issue here.
