I did have another look, BTN is 229/230 with all nodes done (including ephemeral and folklore), all that I can see left are the ones marked 3***. Must have looked at the list 10 times, it is all checked off

miner looks like it can be done without any 3*** (just). I am missing the final book, but it does look like if you gather everything except the 3*** you will just make 150.

That's a big mistake/bug, a very wide gap in gearing requirements for each.
