ArcadiaUtilities was disabled as this is common recommended addon, which makes new players download it once starting game, which might lead to bad first experiences causing in quick quit.
Funny fact#1. Think about how many players moved here thanks to this addon which is a must-have for more than 10 ppl i believe
Funny fact#2. No crashes with AU, 1 crash per hour without AU
Please keep in mind that 10 reports means only people who reported it. There might were way more people who also were experiencing this crash, but never reported. We are supporting addons, but can't promote addons over base game development and experience. As it was said it can occur only during certain conditions, but that's already enough reason to temporary deactivate it. Hopefully addon author will be able to add checkers for certain plugins of this addon so in future there will be no need to deactivate whole addon at once in case any important issue is found.
