Hi, In my game I have about 10 NPC prefabs, each prefab would load in 50-200 ms on Android in Unity 5.6.1. After I upgraded to 2017.1, each load takes 3-4 seconds, and all NPC objects are loaded in 45 seconds. (!!!) I tried Resources.LoadAsync and referencing prefabs in ScriptableObject, but none of them helped. If I removed all references of animations from prefab (Avatar, Clips), loading time went down to 9 seconds. Each NPC has 3 MonoBehaviours, Animator, BoxCollider, RigidBody, SkinnedMeshRenderer and few bones.
