I've gotten to the point where the numbers are just getting bigger, as the prestige is not implemented. 
Trying to get to "infinity," for a few things, but I'm assuming I've hit end of current content.
Will the save still be valid for week 16 or should I stop now and wait?

I intend to keep old saves valid and compatible with new versions, no worries.

Thanks! Just working on finishing "infinity," for swordsmen, then the other resource! Great game, super fun, excellent story writing.
