Invisible and not targetable monsters in Hive Fortress with Memory influence

If Hive Fortress spawns in a map with Originator's Memories influence, there are invisible monsters in the hive where you can see the health bar and mods during mouse hover but you can't target them.

They continue hitting you and spamming their skills though, so you die quickly (especially if you are an ES leech build)

I literally just ran into the same issue.
A bunch of fast "It Crawls" that were invinsible on a Originators Desert Map...

I cant seem to target them with Arc. Only with autotargeting skills like Orb of Storms and the Graft casted Wreathed in Light.

Also, i am the same, ES leech...
