Night Lotus Gloves MTX turns respawned enemies invisible

Using the final tier of the Night Lotus Gloves MTX causes some enemies to turn invisible. I first noticed this on legion rares in maps, but it's especially noticeable with the elder portals in the normal elder fight. The portals are initially visible, but they become transparent when they respawn. I ran an elder with and without the gloves MTX to deduce that they are the cause.
