Finally fixed the "leaning Lux" issue! Sometimes after smashing a crate, Lux would walk on an angle (usually leaning backwards). I finally found the cause of this and it's definitely fixed. Thanks to everyone who reported the issue, it help me track it down. :)
Repositioned Lux's teleport effects so they're correctly centred on her.
The table supporting the hourglass in Mogwai was not being rendered, so the hourglass appeared to be floating. Fixed.
Improvements
Added a new message during key remapping to prompt the player to press a key to assign it. This makes it clear that the new key is assigned by pressing it on the keyboard, not by clicking it on the screen. I also added a new message that's displayed if key remapping is cancelled by pressing Escape.
Performance tuning
Optimised the main camera's anti-aliasing parameters for better performance.
Recreated the vegetation in Saint Sophia to use Unity's new multithreaded jobs package and burst compiler.
[Dogan Outpost] Changed Dogan Outpost to a night scene. This improves performance by drastically reducing the number of shadows that need to be drawn, since objects in the distance can just be left unlit.
