I have set my price source to Auctionator and whenever there is a new update to the addon, it gets defaulted back to TSM. Can this be changed so your choice is still saved when updated?

When you load onto a character where Auctionator is not loaded then CraftSim will load and set TSM as your default. When you then log back to a character that has Auctionator loaded, tsm will still be your default
