do you have the boolprop snapobjectstogrid false cheat code active?
get the cheat code window uo (CTRL + SHIFT + C) try typing in
boolprop snapobjectstogrid true, and hit ENTER.
that code will often do things like that if the moveobjects cheat is not active.
(also, if you have the hack named "see them 2.3", unclick the window with the plants so it shows a red X. it will stop the cheat code above from being active when you start up the game.)
Yaaaayyyyy thanks
