Looking deeper into what was happening, some explanations can be found. Unfortunately, what was going in side-chain stuff is not available for analysis.
There are explanations for the Treasury as well and derail of CoinEx, in which you obviously blamed me without explaining anything once I got from vacation. However, I think clearly read the cause for derailing.
I was receiving messages that some chaos is going on, and I definitely did not like what I've seen and what releases have been made. I've never seen results of external audits even though requested that from around Sep'19 iirc, and I guess there are many shady parts.
Energi Core, I know you are messing with something more which would explain much, but there are some fixes I've done before the stuff started:
https://github.com/codingfuture/orig-energi3- A complex fix to restore dynamic checkpoint functionality and tolerate large number of items
- Changed the default connection/dial to 128/8
- Restored DoS functionality with tolerance to strong old forks and limited number of stake dups
- Accidental duplicate stake fix in miner
- Default nonce-cap of N=10,000
- Miner bail out feature to exit on N=3 own blocks in a row from current tip (configurable also at runtime)
- Something more
You probably already known todo:
- The BlockRewardV2 needs to be created to send remaining from previous ops into the Treasury like MNRegV2. A big redesing would be to implement retrieval of address:amount parts for processing as consensus txs for extra safety.
- MNRegV2 assert in reward() loop spoils everything, but msize() boundary check is required alongside gasleft() check to minimize surprises in the unavoidable loop (mostly the case abort in mass inactivated after jump into a wrong chain).
- I guess you came to a solution for merkleroot problem already
- I guess something else got reported indeed, but it was never communicated to me due to Bashful's play behind the scene.
Don't be dicks like me

Kudos to Bashful - our shuttle diplomacy shitstorm event organizer and regular multi-face shitposter in the thread.
P.S. You know that my position is that all papers signed were extortion and cancel each other, and you know pretty well why.
