[loomgithub]

Bot couldn't gather anything in Vanilla 1.12.

Steps of reproduce:

1. Create an GM level account.
2. Create two characters(name testaaa & testbbb) in this account.
3. Use .levelup 59 to these two characters.
4. Use .modify money 99999999 to these two characters and let them learn Herbalism.
5. Login testaaa, use bot command .bot add testbbb, and then inv testbbb, let testbbb follow testaaa.
6. Move to a silverleaf(item ID:765) or a peacebloom(item ID:2447)
7. testbbb won't do anything to herb.
