Does it happen for particular wstheme files, or random?
if it happens for particular ones, can you tell me which one, or upload it here maybe.
Does it also happen if you load the theme on the gear directly?
Can you estimate how many wstheme files you have on the gear at the moment?
I heared from a user that ran into simular problems after loading 100+ wsthemes.
Most of the time this Roley Submariner only loads the hands: http://gearfaces.com/?p=7749
Once in a while this Rolex Submariner 2.0 does the same: http://gearfaces.com/?p=9485
I can't get the Roley Submariner to load in Watch Styler either, in case that is related.
