Scratch that, I figured it out! It was an exception error that was caused by turning the mod on and off for a few tests and updating other mods and reloading the world multiple times. It causes the Seaweed time tracker to go ballistic and crash the game. The only way to fix it was to turn off the mod, break all the seaweed, and load it back up with the mod on and replant it. In addition, if there are any growing herbs or plants when the mod gets turned off and turned back on, they lose their growth tracking timer, and need to be broken and replanted.
