PHP Code:
addtiledef image,levelstart,type;
specifys the tiles images for all levels that start
with 'levelstart' (0-standard type,1-new order)
Since you're using the new type of tileset, make sure you use type 1 instead of 0.
Type 0 is for classic tilesets like pics1.png or the N-Pulse tileset.
Type 1 is used for the new layout.
If this doesn't help, you may just have to experiment to find the correct placing for bushes and similar manipulatable (is that a word?) objects.
