SpeedTree billboards are not visible after cooked project

Hi,
after cook my project, SpeedTree billboards are no longer visible in game. It looks like material broken. It is default SpeedTree sample model (Broadleaf).

Anyone could help me?

It’s probably bug! I moved this tree to another folder and it works! (?!?!?!)

hi… i’m currently getting this issue… which folder was it at and where did you moved it?
