You're Hired CUT ANIMATION (Block sequence) (Patreon)

So a while back I found some GREAT audio by Angeldark and wanted to make an animation with it. But for some reason SFM did this glitch when I was splining it that made the entire thing unsalvageable.

Anytime I added a keyframe past the 5 second mark the rest of the block would change. Every single pose would be different and the next thing I know, Kazooie turned into this creature. I tried undoing thing, making a new save to try and fix, and just going through the entire thing once to see if it'd just MAGICALLY fix itself. But sadly there was no success. It sucks because I had a LOT of passion going into this one but things just shat the bucket from the get go after I was done blocking it.
