Dream Corruption achievement doesn't complete when corrupting a map into a Vaal Temple map

Dream Corruption achievement: Corrupt a map into a Vaal Temple map

In Sentinel league, I used a Vaal Orb on a Tier 16 map and it became a Vaal Temple map.
However, the achievement Dream Corruption wasn't marked as completed.

I corrupted 3 t15 and t16 maps into Vaal Temple maps and didn't get the achievement. The maps were in my map stash tab.

When I moved some t16 maps into my inventory and corrupted them there, I got a VT and the achievement on about #10.

I think there might be a bug caused by the VT not being able to be held in whatever tab the map was in, and it being picked up immediately.
