Hi guys,Maybe I am doing something terribly stupid but FUEL is not correctly serializing a Set. I uploaded a video so you can check:https://youtu.be/wAQgbkqAXtkAs you can see, there is 1 new object in the Set, on serialization the file grows, but on materialization the new object is not present.Any hint?Using Pharo 5 here.Cheers,Hernán
