This is a note to @Andrebc , who asked that very same question in the badge thread
why did we ended the event already?
1. long time players have completed though unpicked collections for most events.
2. and also a lot of building items in the warehouse - it took me literally 5 seconds after the beginning of the event to reach stage level 3
3. a reliable set of neighbors also helps - for baggage tags for example
4. knowing which bonuses should be activated is a must
Also - but not that important - the event started on Friday, not yesterday...
