C2,
The Lobster and Crab Farmer ran all night, with no problems at all. I see where you are going to add the possibility of allowing you to use a Legacy Ship where you can place 4 traps on each side of the ship for a total of 8 traps. You cannot mark a rune on the Legacy Ships, but need to target the ship key in order to recall to it.
Also, if I am not mistaken, the regular Lobsters and crabs do not get used by the Quests, just the named ones, so I have been tossing those away.
