Sounds like there are a lot of bugs dealing with paths that are not a particular path. For me I

1) Let the woman kill the Goblin in the cage

2) Stole the Druid Idol and gave it to Mol to sell in Baldur's Gate

3) Killed Kagha in her room and killed the druids

4) This caused the remaining druids and some of the guards to fight the tieflings.....which caused Zevron to die

5) Went to Goblin Encampment to kill Spike for Wyll. Deceived my way through and used the Illithid powers to get into the encampment with ease. Killed Spike and saved Volo. Snuck around to find Mintahara and killed her.

6) Killed Dror Ragzlin and then Priestess Gut. Went into the Underdark for a bit but came back up and fast traveled using the glyphs to go back to the grove.

7) Druid Halsin was there, despite me not having rescued him, and he said that I should get my reward and he'd see me in the morning about getting healed.

8) Talked to Zevron's corpse to get orders for the Tieflings and talked to their new leader.....was told to meet them at camp for celebration..........and they never show up and thus the game doesn't register that I've waited a day (four days now) and Druid Halsin isn't coming to talk to me.....he's stuck in his "I'll see you in the morning"
