Greetings, nephalem!
Our first PTR patch is coming up next week. In anticipation of this update, we want to give you a heads up that we will also be wiping progress on the PTR when the patch is issued.
This is because we want to make sure the overall 2.3.0 changes to Adventure Mode are thoroughly tested. However, a bug in the first PTR patch allowed level 70 crafted items to be equipped by low-level characters. This was unintended and skewed progression at the start of PTR Season 4, making a wipe necessary to ensure that it is no longer factoring into the leveling process.
We will be closing and creating a new Focused Feedback thread for Adventure Mode when the patch is deployed to collect feedback untainted by this bug. While we understand that a loss of progression can be frustrating to some, its important to remember this is the nature of the PTR. Its intent is to facilitate testing, and we love seeing all your dedicated and thoughtful feedback.
Thank you for all your enthusiastic feedback and testing. We look forward to sharing our upcoming changes with you!
