The mod is currently outdated for 1.16.5 version , as it no longer contains the vampire and bloody trees , rather it contains the dark and cursed trees which are only in the 1.19 integrations mod , please release and update for it.
i would also love to get dynamic trees integrations of the werewolves addon , thx!

Thanks for letting me know, I wasn't aware they backported these changes. I will update the old versions as soon as I can.
