Truffle and solidity tips and tricks - nonce error with Metamask

If you use truffle development environment with Metamask as well you can often get the following error message: "the tx doesn't have the correct nonce". The problem is that you probably use the same accounts both from truffle development console and from the Metamask UI.

So what you have to do is to reset the Metamask account: Settings - Reset Account.
