[Bug] Signing a multi-call TX throw back an "nounce" error [user-reported]

[Bastien-Satochip]

This is a [User-Reported] bug regarding "Uniblow Ethereum client"

I have encountered an issue when claiming multiple rewards in one TX, I get a nounce error.
From what i can understand it's related to the reuse of the nounce instead of nounce+1

Here is a few information gather from the user:

"it was when you reuse the same nounce for several transactions."
"So if you have a pending tx and try another one It might occur."
"It's just a local problem in your wallet."
"You need to keep track of it. usually the wallet asks for last used nounce and add 1 before sending tx."
"But we spammed it so missed it some times."

As i understood and could see happpening

1. I logged into my portal via walletconnect
2. choose the rewards to claim to claim, and what "deposit box" they need to go to. (What really happens is multiple TX being bundled into 1, and future distributions will only require 1 single TX instead of 1 per reward)
   Everytime I tried to do 2 or more the TX failed with some "nounce" error, it really didn't tell much

And based on that, the guy provided the above info.
