I recognizid the problem while moving from one house to another. I stored the Elemental Display Rack with all elements collected in within my household inventory. I stored the fridge with the catched fishs as well. At the new location some collectables have been lost, other(elements/MySims Trophies) lost function and everything wasn´t in Sims inventory while moving got removed from the collections list.
Moved again, same thing. Everything that isn´t in Sims inventory gets removed from collection.
