Adopted block is not shown on the chain - why?

In fact, it is not even shown as in a slot battle. Simply another block from NORTH took its place. This is very strange. Can someone offer some insight here? Really appreciate it.

The cardano node version is 1.34.1 for both producer and relay.

The log from the forged block:

Below are some suspicious logs that may suggest the chain is forked and switched a few seconds later.

A

However, the forked is not detected as a battle by pooltool.io. See pic below. As you can see, NORTH produced a block in the schedule slot, 67775073.

Thanks!

Hi @Jun_Sun,

If testnet is an indication, then those may be preparations for the Vasil hard fork.
