Describe the issue
Mining SHA256 via wallet becomes stuck though i never got left behind or banned. Feels like when the 5 in a row limit is reached while on sha, wallet swithes all resources trying to build the 6th but it gets rejected, creating a loop.

**What behavior did you expect? **
Mining SHA256 should not stop syncing the chain.

Mining is stuck at block until you stop the miner generatecontinuous false
and then restart it generatecontinuous true 1

How reliably can you reproduce the issue, what are the steps to do so?

What version of the Veil client are you using, where did you get it (website, self-compiled, etc)?
Qt wallet

What type of machine are you observing the error on (OS/CPU and disk type)?
Windows 10 - Ryzen 3900x
AMD r7 3700x

Any extra information that might be useful in the debugging process.
I have tried with both staking enabled and disabled
