Fishing cast result visible after switching first-person view and jumping near pond

### Build version
v0.164.0-alpha-main

### Issue Description
After switching from first-person view and jumping around the pond, the final result of each fishing line cast becomes visible on the pond. Results that should only be revealed at the appropriate moment in the fishing gameplay loop are prematurely or persistently shown.

### STR (Steps to Reproduce)
1. Go to the fishing pond scene (parcel ~(2, -4))
2. Cast a fishing line
3. Switch from first-person view to third-person (or vice versa)
4. Jump around near the pond
5. Observe that the result of each cast is visible on the pond

### Expected Result
Fishing cast results should not be visible until the appropriate moment in the gameplay flow; switching camera view and jumping should not expose them.

### Actual Result with evidence
After alternating between first-person view and performing jumps around the pond, the outcome/result of each cast is visible on the pond surface.

Log observations from the session:
- Scene `(2, -4)` reloaded multiple times (possible scene instability during jumps)
- Multiple `Curl error 42: Callback aborted` errors logged
- Active feature flags include `alfa-double-jump` and `alfa-gliding`

### Reproduction
Unknown (Reproduction Index: 1/10)

### Operative system and additional Notes
- OS: Windows 11 (10.0.26200)
- Hardware: AMD Ryzen 5 5600G, NVIDIA GeForce RTX 3060 (12 GB VRAM), 48 GB RAM
- Unity: 6000.4.0f1

Start by reproducing in the fishing pond scene at parcel (2, -4), alternating first- and third-person view and jumping while checking when cast results appear. Compare the observed timing with the expected fishing gameplay flow; done means cast results remain hidden until the appropriate reveal moment and are unaffected by camera switches or jumps.
