Seems the cap for resources is at 198 with easy-craft. A little limiting on larger projects, but pretty sound for most stuff you need to do on a regular basis like weapon/tool repairs. The real issue is how often that one will crash the game. There's a strong chance it's having issues with how to handle thralls, especially resource-generators (blacksmith, carpenter, etc.) I've tried a few different ways just to see how long it can run and it always crashes when I have a blacksmith active, and (oddly enough) my dancer.
...Might be time to look at updating.
