Failing to add contribution (false negative alert)

[raucao]

Just happened with one from Gitea (see kredits@kosmos.chat):

I tried to add a contribution for raucao for https://gitea.kosmos.org/kosmos/gitea.kosmos.org/pulls/45, but I encountered an error when submitting the tx:

replacement fee too low (version=4.0.36)

Quickly checked HAL's wallet, and it contains enough ETH for any amount of fees.

Weird: even tough there was an exception and error alert, the tx was actually confirmed: https://kredits.kosmos.org/dashboard/contributions/414

"replacement fee too low" is typically when the same transaction is published twice - or a transaction with the same nonce that is.

There was no other tx being published close to the same time (or even this entire day). So it must be a problem with nonce management (#28) in general?
