Confused about LND derivation of node's payee pubkeys Okay. A short summary of the problem: I'm trying to derive the root key from LND from the aezeed, but I can't get it right.
Assume the following seed (aezeed):
ability quality bulb clap quality piano focus ivory trust essence improve book antique analyst double equip reason venue jazz zoo host potato harvest divorce

For which the following root keys result:

To check if these are correct, we derive the node's payee key (identity pubkey), which is m/1017'/0'/6'/0/0
results in 03bb9f9f7734ca9da4ec06543d32456384f878303305a72979e7316825e00749ad
the problem is; the above seed results in 039e625ffe5325224e6273fc5e0afe59f7ec82cb90add45e76f34cfff9efdcac60
(as per LND's getinfo)
Anyone who can spot my mistake?
Wrong cointype. I'm assuming mainnet = 0, and testnet = 1,  although I can't find any documentation on this.
m/1017'/1'/6'/0

gives the correct identity key.
