Refresh draw on TyCache loader change

[mitchfx]

I’ve noticed for ages that when you load a new cache version (or hit reload if old cache was overwritten) in an existing TyCache object, the viewport display of the particles/mesh don’t refresh until you scrub the timeline again. It would be great if loading the cache would force a redraw so you immediately know it worked. 

Thanks,

Thanks Mitch, I'll look into it.
