Wrongly received achievements.

I'm not sure what the second one is but I definitely don't have the 1st and 3rd one here.

What rank do you have in the Beyond? Regarding the second one you have, it is for unlocking the Reality Engine for the first time (where the hypercube and permanent simulation upgrades are located)

Have you played the beta version of the game recently?

Never played beta, no. I'm rank 7 in beyond

I didn't have a finished constellation at that time

In principle, achievements earned on Steam cannot be deleted, so if it doesn't bother you, it shouldn't be a problem. Anyway, thanks for reporting this bug
