Datapack Stops Running

Not sure if this is a Realms issue or a MCJE issue. But the datapack I have running on my realm randomly stops working. Usually lasts a week or two, as far as I can tell. At some point when I log in, I'll notice it isn't running anymore. I realize JE1.13 is coming out soon, and might fix this issue. So if it gets put in the resolved bin, I totally get it.
