Where does Flashback mod takes its LOD files?

I use flashback mod for replay recording and when i play singleplayer, in the replay, is see the LOD loading fine. But on multiplayer replays, it's doesn't render LOD at all. I use DH 2.3.6 and minecraft 1.21.4 So my question is, where does flashback load it's LOD? Or it's a bug or it's not in saves or the DH server data. I tried using only DH and Flashback, no shaders, it's the same results
