Server Sided Sirens cause server to crash

[frosty0999]

When you use a server sided sirens script it will cause the script to spit out an error and then the whole server will then restart. I am using the latest version from the discord.

Unhandled exception in Mono script environment: System.InvalidOperationException: Collection was modified; enumeration operation may not execute.
