Bulbous Lightbugs won't follow their "leader" through wormholes

If you have a Bulbous Lightbug in your inventory and jump through a wormhole, any free Bulbous Lightbugs that are in "formation" will not follow and will instead stay behind.

Also, sometimes, when you drop lightbugs to have them orbit you, they won't "detect" the lightbug in your inventory unless you take it off your inventory (by, for example, dropping the backpack with the lightbug in it) and put it back on.
