Expected behavior: When you toggle the 'sphere' option in your action menu, a sphere should appear and disappear in front of you.
Actual behavior: Nothing happens locally.
This avatar contains a gimmick used to detect the T-pose calibration state of the avatar (this was to work around other bugs that were present in prior versions of vrchat; I haven't confirmed whether those are still present). This gimmick works by having the calibration layer enable an object with a secondary animator, which then changes the weight of a playable layer on the main FX animator.
In the released version, as well as open beta versions up through build 1346, this works reliably. In build 1347 and 1348 , this breaks - the calibration animator seems to be active even though the object containing it is not (the XDresser__Calibration Detector playable layer in the FX controller's weight toggles between 1 and 0 because of this).
