I logged in and received a black screen, I didn't even get into my homeworld.

Steps to reproduce are unknown. Occurs randomly (only once after Instance Capacity Stress Test Pop-up, after being crashed by an avatar that got taken down).

Additional info: "Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection's state is no longer correct."

The issue resolved on its own with a client restart.
