Should hopefully be published later this evening

There's a note about the explorer notes only registering 99% for some people and there is currently not fix or workaround that's been found.
I'll update that as soon as one is known.
The warning message:
This is one of the buggier sets of achievements. They may unlock with no issue, but also may require you to delete your save, forcibly reboot the game and re-enter the code a couple of times. If this occurs, finish out the rest of this walkthrough first, then come back to this. For me, the first achievement popped after a couple of minutes waiting, then the others popped together a few minutes after that.
does not indicate that there's the 99% bug that has no fix. After reading the message, I decided to go through with starting the game because the warning suggests it'll pop eventually. It even says 'the others popped ... few minutes after that' but you don't have the achievement yourself either. Would it be possible to update the warning message?
