My level doesn't seem to be increasing from level 50 and I play the game every day, any ideas what is causing this also stables not producing yetis in order to collect map pieces and therefore move forward with a task
That sounds normal to me... I think the key to getting a prize is to be in your game as much as you can. Drops range between 1-3 items, but are mainly 1. Keep going a lot of players have their peacock now, so it is possible. Events are supposed to be challenging and hard...they always have been. It's ok not to finish an event or even join in. Some players put a lot of pressure on themselves. That being said, I really hope you get your peacock! Good luck!
I'm sorry you're experiencing trouble with this It's a random chance you will or will not get a particular resource each time you harvest from an item, so even if there's a high chance of something dropping there's always a chance it won't (excluding items with guaranteed drops).
The item which will for sure always drop Living Wood is the Living Tree. The next-highest chance of a Living Wood drop is from the Bidding Booth, followed by the Magic Garden.
I hope that helps!
