I scripted my own character bone scaler a while back, and got this mod to account for view height and such. Only problem is it doesn't work. I understand this only automatically works for the default size of the playermodel, but changing it manually doesn't work. Changing playermodels doesnt affect the height either. The walk and run speed functions are also broken. I ended up coding my own addon to fix height (which sucks to use), but i would love if i had a nice GUI to use it in (im lazy). I've deactivated every other addon, commented out large parts of my code, uninstalled and reinstalled the addon, closed and reopened gmod, and rebooted my PC. This is really frustrating and I want to know if theres any way to fix this (also tried finding the addon in my files to try and 'borrow' some code, but it doesnt show up)

TLDR;
Things that work:
-Hull
-Health
Things that dont work:
-Camera Height
-Run/walk speed
Fixes i've tried:
-Uninstalling
-Deactivating addons
-Commenting parts of my own code that might interfere

Error codes:
Bad pstudiohdr in GetSequenceLinearMotion()! (x2)
no idea if this is from this addon but i didn't see it before so im going to assume so
