I always play in windowed (fullscreen), and I tried just normal Windowed, but that didn't change anything. I still got the error.
I have a problem with this specific error... it does not allow the client to do anything [2:16:38 PM:025] System.NullReferenceException: Object reference not set to an instance of an object. at Styx.Logic.BehaviorTree.TreeRoot.Stop() [2:16:39 PM:041] System.NullReferenceException: Object reference not set to an instance of an object. at Styx.Logic.BehaviorTree.TreeRoot.Tick() at Styx.Logic.BehaviorTree.TreeRoot.Run() [2:16:39 PM:041] System.Threading.ThreadAbortException: Thread was being aborted. at Styx.Logic.BehaviorTree.TreeRoot.Run()
