How to make server roundsystem script reliably see workspace children?

After 2 players join session, Roundsystem script fails to accurately see whats inside Workspace causing dead servers due to the script not continuing to run.

I've tried pcall but that causes specific levels to repeatedly run.

This is where it errors out due to the fact that it cant see jack in workspace unless there's only 1 player in the server.: line 51
