That's the worrying thing, I've made sure of both those things. One thing I noticed, looking in MO it appears that the tree billboards are coming from Trees and Flora Merged rather than the actual billboard mods, and I have no idea why because Flora Merged is lower than them all and the left pane says it's being overwritten by EVT Billboards, your billboards and SFO Trees Only. Edit: Scratch that, the LODs in the actual DynDOLod folder *appear* to be coming from the right places (DynDOLod Resources, Trees and Flora Merged and *primarily* EVT Billboards) so I really have no idea what I did
