MOHAWK: MYST: Inside Shed, Boiler Needle Animation and Tree Movement Sound Not Playing Correctly

[wataniyob]

When inside the shed with the boiler on Myst island which raises and lowers the tree, multiple issues occur when the boiler is on:

• The needle animation does not properly play, going from left to right when the pressure is turned high enough or going from right to left when the pressure is lowered enough
• The sound of the tree raising up one step and dropping one step is not audible inside the shed, instead only audible outside
  1. The only time both the needle animation and the tree movement sound correctly play is when the pressure is turned to max, you open the pause menu and then resume the game (before pausing the game, neither animation play correctly)

Steps to reproduce:

• Get the match from the safe in the shed after unlocking it with the right code.
• Light the boiler
• Turn the wheel to increase/decrease the pressure

Here's a video of the needle moving and tree moving sound effect correctly playing from the Myst Masterpiece edition for reference:
