Strand Map Gone

I had approximately 15 T14 Strand maps in my Stash Tab. I completed a Strand Map and after completion, I went to get another Strand Map and they were all gone.

Same thing just happened to me. I instead have two odd looking corrupted Strand maps in the tab.

After completing a t16 Strand map with 4 sextant mods, around 40ish t16 Strand maps disappeared from map tab.
The Sextant moda are:
1. additional monsters that convert when killed
2. players and monsters take more lightning dmg.
3. additional corrupted vaal monsters
4. magic pack size

One corrupted Strand, a former Whakawairua Tuahu, dropped on the last maps and is now the only Strand in the tab

Strand is the only favored map i set.

try removing the strand maps that is shown in the tab, change instance and check again.

XD
thank you very much!
removed the corrupted 8-mod map, reloaded area, and voilá, all starnd maps are back (are visible again) :)

you are most welcome. :)
