[Tidal Tubes Future 2] No transparency on top layer of collapsing platforms

[VectorSatyr]

Environment:

• Device: PC
• OS: Windows 10 Home

Steps To Reproduce

1. Run SonicTT.exe.
2. Press 'Start' at the Title screen.
3. Select "Play".
4. Navigate to any save slot that has access to Tidal Tubes Zone Act 2 (Future).
5. Press the 'A' button.
6. Use the arrow keys ('Up' or 'Down') to navigate to Tidal Tubes Zone Act 2 (Future).
7. Press the 'A' or 'Start' button.
8. Navigate the lower route of the level until you come across a bed of unstable terrain.
9. Stand on any section of the terrain.

Expected Result
The terrain collapses; there are no functional or graphical issues present as the terrain pieces fall.

Observed Result
The terrain collapses; the upper most layer of the terrain pieces have opaqueness where there should not be, resulting in the player standing noticeably higher than when the terrain was still 'stable' and ruining the illusion of the terrain crumbling away evenly.
