Dancing around plants

[tige 0]

Hi everyone,
Recently I used the bot on a new small server to farm some plants and I ran into a rather annoying problem.
When my character (a druid in the form of a flight) picks up a plant most of the time he has trouble detecting the exact location of the plant and therefore creates a dance around it to try to pick it up.
First it makes my bot very visible because it's not credible at all if a player was doing the same thing and second most of the time he ends up abandoning the plant because he moves away from it.
On other servers any of my profiles work fine, but on this one none of them work.
Do you have any idea where the problem could be coming from?
Thanks for your feedback.
