Awhile ago experimental changes were made for zm that caused issues with
wait_network_frameI heard the changes was reverted in a recent revision, but issues still occur like zombies not spawning in high rounds, random crashes, power-ups not dropping, etc. Even with vanilla gameplay. A fix was made to counter this issue and so far it still seems it's needed. No issues so far from myself using it, especially in high rounds. Use it if you want to and here is the source.
