I've met this white screen issue:
#1372

and checked lots of solutions but failed to solve the problem, including switch to test nets and get back.

and occasionally I saw this video:

I had the seed words(fortunately)

and I understand that I can restore the origin sets of accounts by the single set of seed words.

I removed the extension, reinstall it, and then it turns out that the main account is intact but other accounts are GONE, and it seems that I've lost tens of ETHs here.

I tried creating new accounts, but I only got new ones, not the ones that I have assets stored in.

QUESTIONS:
so I believe the MetaMask is based on HD wallet structure,
and for some reason the dev team changed the algorithm of generation new accounts from the root seed??

(I'm using 4.8.0, the removed version is still 4.8.0)

Pleeeeeeeeeeeeease help me out of this!!

Thanks.
