I keep coming across an issue where the bollish xeno attack in a group, and 1 of there missile attack ships will become untargetable. Other ships (including mine) can target and sit in the same square. The ship in question of is still fully functional (much to my dismay).
Can't seem to do a screen shot on this new phone though.
But it seems to happen if 2 xeno ships try to land on the same square.
