Sorry, I meant full logs both client and server. However it looks as if the login client may be using vanilla or has additional mods of some kind (more likely vanilla) Make sure the mods are the same and that the client is actually launching regrowth.here is the fml-serverlog

I highly recommend the FTB Launcher. It works wonderfully.
I'd suggest replacing the wither skull with a player head via Botania runic altar recipe (noted in Lexica Botania) It's even better than the wither skull.Like you, I have been wondering what is hidden for chapter 2. This morning, I awakened and did some idle browsing through the quest book before leaving the study. Lo and behold, chapter 2 shows complete! Nothing has changed within chapter 2, but all is done. The last thing I did before going to my repose was to complete the last seeds I needed (spider, creeper, and shards) and craft the Extreme Essence Stone. I then replaced the skeleton skull on my altar with one of the wither skulls I received from the reward. One of those actions must have been what chapter 2 needed.
On a side note for anyone bothered by the demon heart beating sound, the altar range for both power and usage is vertical as well. I have them up in a tree near the range limit. The sound just bugs me for some reason.
