This was working fine previously, and was nice way to improve the efficiency of playing the Starfall quest - but now after placing a stop buff on an otherworldly plant (e.g. while the enriched fertilizer buff is active), you get a message saying the buff has been stopped, it shows as having been stopped, you can seemingly apply a new buff (e.g. the harvest kit)...but it fails to apply. At some point (e.g. after logging out and in again, or a certain time period), it appears that the old buff (before the stop buff was placed) is actually still active!
Please fix, as there appears to be no reason that stop buffs can't be used for this purpose.
(Also I frequently have issues with messages telling me I don't have permission to start a new thread. Took me quite a lot of mucking about to get this to work, including using incognito windows etc.)
