Doing this allows the alarm to potentially be set to 0.
In some if not all cases this prevents the alarm from ever activating (might depend on what event it is called in, not sure).
So use irandom_range(1,x); instead.

I can't speak for Fair and Square but Zeta's a $5 game that's been averaging $2 per sale, so I decided, why not just roll with it permanently? So I asked on the RTS dev discord if anyone wanted to bundle at -60% and the Fair and Square dev said, sure, why not? So here we are, two solo developers trying to find a market for indies somewhere within the RTS genre.
Of course the bundle discount percent is applied to the current combined price of the bundled games, so sometimes (like right at the moment with F&S being -40% presently) you can get an even better deal. Sorry if I'm stating the obvious here; with the last bundle I was involved in putting together, there was some confusion with how Steam bundle pricing interacts with other discounts because it is displayed in a rather confusing way on the store page.
