Unexpected payment sent message state, outdated addressEntry - marking payment as sent temporarily failed or was delayed
In RetoSwap 1.0.17 .deb Linux Debian I have clicked to confirm that I have sent a non-XMR cryptocurrency to a taker. But somehow it said something like that the message was saved (not delivered), like if taker is offline. The taker told me I need to mark payment as sent, yet i did it already and now the button was gray/inactive. So I have clicked to restart RetoSwap and I could see that the trade is complete and i can close it. The Haveno.log contained [some warnings, here](https://bin.disroot.org/?a4ac6d70f7c091fb#HJ1U6p9PJkzfoRBg3cmspZX6p61Sa9vk2UrGLTv6Ndjm).

Any idea what may have caused this and how to avoid user ending in a state where he needs to mark payment sent, but the button is inactive? Maybe app has been retrying to deliver the payment confirmation on the background, but the user does not know that it is doing anything.
