Level 31 and 32 characters are only spawning level 1 enemies in Smuggler's Rest, which is impacting their ability to acquire Doubloons from the landscape. Additionally, the Crystal Cove Collection Challenge is not awarding its proper gems when set to level 36 or 37. Both of these issues will be corrected in the near future. Higher level characters can get their proper gems from running the challenge at CR 35.
We are currently working on a fix for both of these issues, and we will have more information about a game update in the future.
