I just updated my cuffs, and now my arm arm / thigh cuffs do not rez.

Hmmm have you activated your arm/thigh cuff plugin yet?

Remember, every time you set up a new set of cuffs, it is "zeroed" - it does not know that you have plugins (even if you ran transfer from a previous HUD - that transfer only transferred settings/stats, not the cuffs themselves).

To fix, simply activate your plugins by wearing the activator and following instructions.

Remember the rule:

setup = activation

that is, every time you run setup, you get a new set of serialized cuffs, and you need to activate them accordingly. You can't transfer old cuffs over from an old HUD. Plugins will only be transferred if there was no toy setup.
