Harvest boss bug

Sometimes the harvest bosses get stuck in the mob spawning phase. Which forces to just abandon the whole harvest, since you can't continue harvesting while the node you're doing is still active. That can lead to quite the losses scarabs wise. It seems the issue occurs, when the boss starts to transition into the 'standing upright and spawning mobs' phase, while theyre near/on the harvest turret in the center. The boss seems to not be visible at all while doing this. The mobs are simply spawning from a spot, while the green effects are going on, the exact same way it would be happening in the 'standing upright' phase, but the boss is gone. Also, the yellow boss constantly ignores the fact he's been 'phased', and simply continues fighting (kinda like Izaro).
