Problems with Gold Key puzzle in E4M5

[Chaelrishe]

Tested using Quakespasm 0.96.3.

While trying to finish this particular puzzle, I ran into multiple problems, some which appeared on my first playthrough, others only upon reloading that save later.

• It was possible to pick up all three keys without pressing all three of the associated pressure plates, resulting in some of the room triggers not activating, such as enemy attacks.
• After using two of the keys, the bottom two bars of the central cage were open, allowing me to squeeze inside without collecting all three keys.
• The green bars obstructing the central hole did not open under any circumstances and touching them prevented me from running-- I could still use mouselook, but I was unable to move. The only way out was noclip.
• By noclipping past the green bars and into the hole towards the white button, I was able to press the button, but could find no way of doing so and surviving due to the crusher. The bar blocking the way out through the back has a texture suggesting the necessity of a fourth Gold Key, which may or may not exist in the map as it is. Upon reloading this save on a different day, yet another bar appeared here which would have prevented escape even if the Gold Key bar had been removed.

I do not believe that any of the potential changes here were the result of running system updates as I am using the mod version of LibreQuake.

Assigning to myself, I will take a look at resolving these issues.
