Testing on the newest Atlasaurus build 7.1.9.10326512121 it appears the reset skeleton does not appear to be working as intended.
Wear an animation that changes bone position.
Remove/stop animation.
Note that doing Avatar>Reset Skeleton does not reset skeleton.
Doing right click on own Avatar then Reset Skeleton does reset skeleton.
Also introduced with I believe Maint-C was the ability for global reset where when you reset your skeleton, other people would received the reset command as well.
Tested with both people on the above Atlasaurus build this does not appear to be working where when you reset your skeleton from the right click menu, only your self resets. Others do not get the reset command.
