Achievement bug?

[Myyri]

Hey! I have done literally everything I can think of, to get this achievement C1 | The N. Trepid Crash Bandicoot!

I have all gems from Crash bandicoot 1, 2 and 3. I have done all the time trials with gold or better, and still don't have that achievement. Still says 73/74 for me.

Any ideas?

For some or no reason, there is no 3 additional achievments for completing all. You miss some else.

Crash Bandicoot 2
C2 | Cortex N. Furiated

Hidden achievement, mouse over to reveal:
Just "forget" it. Repeatedly.

For this achievment you must start a new game (you can keep old saves, i guess, ofc you should do saves manually), go to Level1 and end it without getting Crystal and Gem (aquring Gem lead to N.Brin scene). Repeat it agin for another Cortex scene.
I forget that detail... Or maybe you can get Gem. Maybe Cortex scene > Brin scene (so for main playthrough better to skip both items for not missing any important dialogues for just non-canon Cortex scene).
