According to the wiki page for Private modules all players should be able to require() private modules named MainModule. And yes, my module is named MainModule. However, recently I discovered that other games not made by me would not run the module.
Any help avalible?

A private module will only work in a live game, testing in studio will give an error.
kingdom I am not testing in studio..
How are they trying to run the module?
require(id)
