Webber and the spiderhat

If Webber kills a spider queen and accidentally picks up and equips the spiderhat, he loses all of his spiders and they often attack each other sometimes resulting in losing all of your spiders. The spiderhat allows up to 10 spiders to follow any character so it might be an issue with hierarchy of behaviors. I'm not sure if he only loses any spider over the 10 limit or if he loses all spiders but it punishes playing Webber.
