[Windows] 1.21 Memory leak

When opened the game takes up a normal amount of RAM but after entering a world the RAM usage climbs until the computer moves it to swap space and slows the game down significantly and causes it to crash, and sometimes throw a bluescreen MEMORY_MANAGEMENT error

Even standing still in a superflat world the RAM usage still climbs upwards of 10 gigabytes of usage. 

The used RAM isn't being returned to system.
