There are reports of several issues in 1.9.0 that have been confirmed by QA and our other internal tests. While many different problems have been reported, the major ones are as follows:
* A region crashes during certain IM sessions.
* A region crash occurs on occasion when dismounting a vehicle.
* Inventory items and L$ are missing upon initial login to 1.9.0. (NOTE: Subsequent logins are not affected -- items and L$ balance are fine.)
* FollowCam camera permissions are not being revoked when dismounting a vehicle.
* Avatar camera is "stuck" after teleporting when riding a vehicle
We are working on fixes for these issues now, and intend to deploy both server- and client-side versions to resolve them as we are able. I will post here with updates when more is known!
