After using these macros this morning I think moving tangled weed to the top of that macro will help it not get stuck on this weed for any character that selects tangled weed.

Also I think adding a single macro to till and then plant seeds will also allow seed planting to work, basically due to planting seeds is
/use Songbell Seed (or whatever seed you plant) and so once the character is close to a tilled spot it will plant a seed. (or even combine till, weed and then plant?)
