I finally found it!
I'm adding a screenshot in case it could help someone. Version 0.17 , no mods



The highlighted "00" used to be 01.
Found it just before the chat log and just after a serie of "FF" as someone previously said.

I have been trying to re-enable the achievements on my save game all evening. With no success.
I would be very grateful if someone could have a look at it?
