Are the collections actually used for anything? I can see some of them are used in artefacts, but others are not. Are there any benefits (besides the reward) to having more than one of each collection? I accidentally clicked complete on a collection I already had and it used fixers I needed for another collection. I'm so mad as it took me ages to get those fixers :(
