Currently, in the edge of hi-law city (a vket world from a couple of years ago) a standard on-enter trigger is completely broken, preventing you from progressing without teleporting to another player, and even then, dialog events do not occur. I cannot imagine this doesn't affect a great deal of worlds that rely on this. https://vrchat.com/home/world/wrld_ec86c5f6-90b6-40d8-928a-d405809c3421/info https://vrchat.com/home/world/wrld_4c106750-ecb7-434e-8f87-97ef6f9294ae/info Repro: Simply enter the world and try to see the intro event with Niigo, music doesn't trigger, and dialog doesn't progress. It works fine on the release build. If vket didn't have EX menu to teleport to exhibits or players, the world would be entirely broken- you would never be able to progress past the entrance area. I imagine that other games and gimmicks that rely on the same method we're using would also be entirely broken. Here's what I suspect is the log for the bug occuring: VRC.Udon.VM.UdonVMException: An exception occurred in an UdonVM, execution will be halted. ---> VRC.Udon.VM.UdonVMException: An exception occurred during EXTERN to 'UnityEnginePlayablesPlayableDirector.__Play__SystemVoid'. ---> System.NullReferenceException: Object reference not set to an instance of an object. at VRC.Udon.Wrapper.Modules.ExternUnityEnginePlayablesPlayableDirector.__Play__SystemVoid (VRC.Udon.Common.Interfaces.IUdonHeap heap, System.Span`1[T] parameterAddresses) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.VM.UdonVM.Interpret () [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunProgram (System.UInt32 entryPoint) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunProgram (System.String eventName) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.VM.UdonVM.Interpret () [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunProgram (System.UInt32 entryPoint) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunEventAdvanced[T0] (System.String eventName, System.Boolean mangleParameterNames, System.Boolean canRunBeforeStart, System.ValueTuple`2[T1,T2] parameter0) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunEvent[T0] (System.String eventName, System.ValueTuple`2[T1,T2] parameter0) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.OnTriggerEnter (UnityEngine.Collider other) [0x00000] in <00000000000000000000000000000000>:0 --- End of inner exception stack trace --- at VRC.Udon.VM.UdonVM.Interpret () [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunProgram (System.UInt32 entryPoint) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunProgram (System.String eventName) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.VM.UdonVM.Interpret () [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunProgram (System.UInt32 entryPoint) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunEventAdvanced[T0] (System.String eventName, System.Boolean mangleParameterNames, System.Boolean canRunBeforeStart, System.ValueTuple`2[T1,T2] parameter0) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunEvent[T0] (System.String eventName, System.ValueTuple`2[T1,T2] parameter0) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.OnTriggerEnter (UnityEngine.Collider other) [0x00000] in <00000000000000000000000000000000>:0 --- End of inner exception stack trace --- at VRC.Udon.VM.UdonVM.Interpret () [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunProgram (System.UInt32 entryPoint) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunProgram (System.String eventName) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.VM.UdonVM.Interpret () [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunProgram (System.UInt32 entryPoint) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunEventAdvanced[T0] (System.String eventName, System.Boolean mangleParameterNames, System.Boolean canRunBeforeStart, System.ValueTuple`2[T1,T2] parameter0) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.RunEvent[T0] (System.String eventName, System.ValueTuple`2[T1,T2] parameter0) [0x00000] in <00000000000000000000000000000000>:0 at VRC.Udon.UdonBehaviour.OnTriggerEnter (UnityEngine.Collider other) [0x00000] in <00000000000000000000000000000000>:0
