its a tree that sends lightings... right in the beginning of the game... where you have to use a big elevator to go down, then you see a cut scene of the soldiers talking to wich other, one of them tries to go into begger nest ( i think ) and gets attacked by lighting...
when ever i talk to the tree the game crashes and my pc shuts down
I also dont know what trees are you talking about, but i think the trees you are referering, are later in the game, iam still at the beginning of the game
