Sounds good. Unfortunately, I don’t have a good workaround for you at the moment for the bug. You can follow the issues here: https://issues.unrealengine.com/issue/UE-295433
If it’s something you and your team need to investigate earlier, I would start by looking in UAnimInstance::TriggerAnimNotifies. This is where we determine if the begin and end calls of a notify state should happen.
