CTRL+CLIC on Aegon make Scarab disapear

When I Ctrl + click a map in the Map Device, it makes some scarabs disappear, at least the Potency Ambush ones.

I tried putting 3 scarabs and a map, then Ctrl + clicking the map, and the scarab literally disappears.

Other scarabs I tested just move to the small box on the left (currency storage), which seems normal. But it doesn’t work with the Potency Ambush scarab, and maybe some other scarabs as well
