Atlas progression gone after migration?

I have a character from Phrecia that was migrated to Settlers and then to Standard. Now I want to play that character again in Standard, but when I log in the atlas progression is gone, except for the unique maps and voidstones.

This is the first time I've opened the atlas in standard. Is this normal?

You need to run a legacy map to get the progression of all maps up to 1 tier below that level. It also need to meet the conditions of the tier it is. So if it is a red map, it will need to be rare and corrupted.

If you have leftover maps from Phrecia they should work. Otherwise if in trade leagues you should be able to get a legacy map. If you are in SSF and have not hung on to high tier maps it becomes a problem.

Keep in mind if you are corrupting your old maps, in the league you have migrated to, they have a chance to corrupt into a non-legacy map, so you will want to run one that does corrupt to a higher teir.

Absolute worst mechanic in the game. Number one thing that I think needs to be reworked.
