[2023] A21.1 b16 EXP

Hello Survivors!

While testing we were able to unearth and fix a few more issues.

Here is what changed since b15:

Changes

• Trader POIs are now excluded from the chunk reset system. This avoids issues with resetting player-rented vending machines
• Increased the block range of spears

Fixes:

• Error while saving player file in some disconnect scenarios 
• Argument Exception from hitting object with vehicle
• NRE with GameManager+ freezes zombies and other entities on dedicated servers
