[Bug] Network Protocol Error with Autopet to Mosquito Pet #172
Description
Bug Description
Whenever triggering an Autopet rule that swaps to Mosquito pet, I get a Network Protocol Error and get disconnected from Hypixel.
Equipping the Mosquito Pet manually doesn't result in a Network Protocol Error though.
Also idk if this is considered a crash or a bug
