SPOILER I Can't Start The Quest 'finding The Light'

Upon completing the quest 'Taproot', I had acquired a Taproot. However, when I try starting the quest 'Finding the Light', it says 'You need a Taproot to start the quest' even though I already have it in my inventory. How am I supposed to start it?

 

It is probaly a false or fake traproot, i would suggest to ask a Moderator :3 I recommend @Headset_O or @MrSebbelonien ( add them to your friend list with /friend add [Name] and then /msg )
