Well, your screenshot is pretty self-explaining, isn't it? On the page where you got the script from, namely Greasy Fork, the script was deleted, so you got a pseudo-update that tells you it was deleted. If you look at the page of that script on Greasy Fork: https://greasyfork.org/en/scripts/375672-christmas-town-2018 you see the script was deleted and replaced by AntiAdware: https://greasyfork.org/en/scripts/4294-antiadware
So I suggest you simply install the replacement or if you insist, shout at Greasy Fork, not at GreaseMonkey. GreaseMonkey is just executing the script in your browser, Greasy Fork is the page where the script was deleted. Alternatively to using the replacement, you can also install a previous version of the script and disable the auto-update functionality for that script. For each single script you have available in Greasemonkey, you can choose whether to auto-update it or not.
