You need to have shift drop enabled @tom20219793
as for hovering tree, I just noticed this too, I think something changed in a recent update, I'll edit the delays to stop it hovering again
EDIT:
Just submitted patch v84.0, it will auto-update within a couple hours. Code affected: c1d1 dropping code now works for everyone (was random for some reason) and no longer hovers trees, looks more natural in this update. You should also notice more humanlike behaviours Shoutout to tom for this update!
