We’re aware of an issue with the Simulate Fitting tool in-game that has appeared after downtime today. The team is investigating the issue and we will provide an update when it is available.
As of 14:00 this has been resolved. Please restart your client to fix this issue.
How about just rolling back the previously implemented changes that caused the problem instead of just letting the issue remain active while your team investigates the cause..
