/**
 * The replay system only replays outputs from animation. It does not replay animations and does not replay actual inputs. 
 * This means very often when a desync is detected, multiple corrections have to be sent before the simulation is stable. 
 * This is why we only ever actually use this system for when a player is in HumanCommandMove and HumanCommandFall.
 * 
 * For some situations, such as swimming, it is not possible to ever correct as the water alignment heavily depends on re-simulaton of 
 * animations, which is not happening. With this,  we use MINIMAL correction mode. This minimal correction mode is something similiar
 * to how the old correction system used to work and could lead to situations such as being stuck behind doors. 
 * This is not a problem for swimming.
