Demo, the testnet is facing some kind of environmental issue where nodes get POSE banned when they should not, this reason is causing hold up of the plan to deploy to mainnet, however, the plan is still to go ahead and fork the new code in test while we try different things to address this issue.
Why are you trying to find excuses for the agents?
The code was ready, the network commanded, the version 18 should have contained ONLY the reduction of the proposal fee.
But the agents intervened, they added a tone of irrelevant changes to the version 18, probably they also added the bug you are claiming, so that the comandment of the network to be delayed for one whole year (and maybe more, I afraid that the agents may find more excuses and next year we will celebrate our second anniversary).
Under no circumstances should the network be allowed to decide essential things, the decision power should remain among the agents, and this is another red line of the agents. No one is allowed to cross their red lines, the agents will use whatever cunning, excuse, deceit, money or violence in order to preserve their stinky/deadly territory.
