Sometimes getting newbile block when not newbie.

[tomasbrod]

On testnet sometimes I get newbie DPoR block. This block is known by research reward of exactly 1 GRC. I traced with debugger and found that GetHistoricalMagnitude returns pointer to genesis block when the newbie is created. Its should return pointer to previous block staked by cpid.
This does not happen always.
Why important: non-deterministic behavior, potential loss of research rewards.

It happens on prod sometimes daily or multi-daily I've seen. I see them in my debug logs on nodes as well as local.

Happening now on production network for me. And since the total mint with 1grc newbie boost is not enough to pass mint limiter, the block gets rejected.

ERROR: ProcessBlock() : CheckBlock FAILED

Happened 2 more times on my testnet node. The newbie block was staked just after restart of the wallet.
And I just want to make clear that this behavior destroys the owed research reward.

[denravonska]

What about #332? It would "solve" this :)

[tomasbrod]

I am afraid it wont. You would still get 1 GRC newbie reward, but without the newbie weight boost.

[tomasbrod]

This issue is related to #225.

[tomasbrod]

#225 Does NOT fix this issue.
Edit: Sorry, I had the wrong exe loaded in my debugger.
I added debug print to my PR to show rsaweight. It should match your magnitude.
Your commit @denravonska does fix this. Closing as SOLVED.
