That ‘other’ issue that just won’t go away

For a day I’ve been plagued by another kind of issue that refused to go away. But instead of it being my headset or my computer, it was something affecting my dancers (related to the new mods I had installed).
I had just finished mass-rebuilding every VRC_Inventory of all the base avatars and began standard testing (making sure they’re firing on command now). Most of them were working as expected. Then I went to the all dancers one.. and holy shit my framerate tanked after it loaded up!! What was worse is my wings were folding into my head and my tail was pointed straight up.
Clearly a collider problem.. yet this thing was kicking my ASS!! Even going as far as cloning one of the existing base avatars and deleting the old one, nothing was working to fix the problem! Even deleted the colliders of the base avatar, still nothing! WHAT THE FUCK?! This is an exact copy of a working base avatar!! THIS MAKES NO SENSE!!!
But I did get some funny pictures when it was happening;


*internal screaming face* 🤣😂

Ok, so it’s got to be the songs now. Tried disabling them, and somehow they’re still active! WOW. Made a dupe of the problem and deleted the songs off of the original (knowing this was my last option). Prayed when I switched to it.. the problem’s gone?! YES!! Confirmed issue with the songs. Odd though as I never made any changes to them since what happened when trying to debug a fuckup.
Wanted to see if it was all songs, or a specific one. Tried moving just one of them to the original and uploaded it.
Now we’re getting somewhere! No issues with the song! Testing continued until I finally narrowed it down to ‘Shake It Off’ being the culprit song (no other song was causing the issue).
And THIS.. is what was causing it;

Blue’s floor collider, 10x larger than it needs to be.
This is what it’s normally supposed to be as;

Culprit found! Problem is, both colliders were using the same size. So I copied a working Blue and hand-maneuvered it to the messed up one, then deleted the old one. Song still works just fine.
Uploaded the changes, and confirmed fix! So, that’s about it. Sorry if this post feels it was rushed, but I’ve been working on other projects instead of finishing the ones I already did.
