January 9 Update

Fixed an issue where teammates returning automatically could occur when traversing the map while searching for supplies. Resolved an issue where character models would become invalid when exported as normal saves in director mode. Added the ability for teammates to find flares while searching for supplies, with a certain probability of finding them. Fixed the issue where sounds would freeze when large groups of zombies moved or multiple players fired simultaneously. Implemented multithreaded loading for certain map resources, increasing the speed of map traversal (especially for mechanical hard drives). Added random events in the basement of the northern apartment building in the main city area, enriching gameplay. Increased the triggers for more auto-save mechanisms, such as opening the backpack, opening the building panel, and more.
