Affinities blight tab & map= blighted map disappears

I have map tab and I set up tab with blight affinity but it is not picking the maps. The blighted map disappears, when pressing control click. There are not in the Map tab or in the blight tab or any other tab. Is this a bug?

I have had the exact same thing happen to me! I had a blight affinity allocated to a stash tab, removed it because I wanted to store my oils elsewhere and now as soon as I ctrl click on a map to get it into the stash AND the map tab is not open, the blighted map disappears.
