This is a list of certain addons that won't be added to the collection despite making an appearance in one of SpyCakes' videos. This list will expand when new addon incompatibilities or workshop removals are discovered.

If this was still on the Workshop, Spy would've used it longer. There are alternatives with a similar health icon, such as Half-Life 2 Customizable HUD and BAHUD - Boreal Alyph HUD, but they don't have the exact one. (appears in a lot of videos from 4+ years ago)

The original upload was deleted by its creator. I'm not looking to replace it unless the creator themself re-uploads it.

I know that a lot of people have lower-end computers and I want to keep this collection as light as I can on any realistic/lower-performance mods. If I were to add it, I'd use StormFox 2 instead. (appears in a video, link coming eventually)

NeuroBase addons will not be added as NeuroBase in its entirety was removed from the Workshop long ago from a supposed "backdoor" with "adware". There is a reupload, but I'm not gonna take any chances with it. (appears in this video)

Original was removed. A reupload was just added to the collection as of March 16th 2025, but it might be removed shortly, I'm not sure.

These are specific maps that just don't work with other addons in the collection or simply were removed from the Workshop. The reasoning for its exclusion will follow after its name.

md_oldresidence [Reupload] - Original version was taken down, currently in the collection but may be removed.
