As a temporary fix for the tree, put the tree package file in as well as installing the decrapified sims3pack. It means two trees will show up, but both will work. Well, they do in my game.
I tried, but even taking the tree in packages, it works for a few cycles, but then stops in the interaction taking, and I had to reset it for it to work again.
The reason is that the packages of fixdi usually has higher priority to slightly to the game modificae not the original script?
Putting them both are the same and when he reads the game at random one with the broken link stops?
I ask out of curiosity
