How to unlock the atlas now?

Ran a couple of old t16 corrupt maps not unlocked the whole atlas?

Same here, not sure why tho.

For me only unlocked 128 of 132, i had to run those 4 maps again (all the t16 in the new atlas).

This is how it works. Completing a bonus objective on a map from a previous map series auto completes all maps of a lower tier than the completed map, so you still have to run all the t16's each time.

Was it a legacy rare corrupt t16 map? The requirement for the catch-up mechanic is completing the bonus objective on an old map, not just completing the map.
