🐛 Bugs when `UseClientPhysics = true`

[Froredion]

Summary

When enabling UseClientPhysics = true (with client-side NPC optimization and AnimationController), several NPC behaviors break or behave unexpectedly.

---

Issues

1. Melee NPCs can teleport upward instead of having to jump

• But happens when UseClientPhysics = true

• In some cases, melee NPCs:

  • Teleport onto higher surfaces instead of performing a jump

• This appears to be caused by current raycasting logic

• There may be room to improve how vertical traversal is validated

---

Environment

• UseClientPhysics = true
• Client-side NPC optimization enabled
• Using AnimationController (not Humanoid)

---

Notes

• All issues only appear when UseClientPhysics is enabled
• Server-side behavior works as expected
• Happy to provide repro steps or test builds if needed
