I had Glut in my party when I defeated the duergar down by the beach, so I started playing around with his raise dead ability. The first one I tried to raise, I got the prompt that you'll have to wait for it to take effect. I tried a couple more but I got no indication that he'd done anything. I only found out that it had worked when I rested and came back and there were three undead minions. Which leads me to my second problem:
One of the creatures I had raised was Gekh Coal. As soon as came back from resting, it immediately triggered a partial dialog from Gehk - no audio but the text gives you the option to leave or what sounds like he's offering a reputation award. If you select that option, it opens up a trade dialog. Now, where he got anything to trade is a mystery as I had looted his corpse, but he had a handful of gold and some non-magical rings. Later on as I was bringing my party to the tower, this dialog randomly triggered again, same options.
While going towards the tower, another strange thing happened. Not sure if this is related but I will note that I hadn't notice Glut had gotten stuck. The route I had taken required everyone to jump a small chasm. I apparently missed him and didn't notice until I was just outside the visible range of the arcane turrets. I switched to him, had him complete the jump and then switched back to my main character to start dealing with the turrets outside the tower. I destroyed the first, moved up the rest of the part (including the undead Glut had made) and then went to destroy the second one up the steps. I destroyed that one but after it flashed up the critical hit d20, Glut and the undead were no longer in my party. The undead were standing around and Glut was now back at the myconid colony.
This last one is a complaint more than a bug. It's been made on other threads but I'll add my 2-cents here. We really need an option for the group to auto follow the leader, even when it means jumping, flying, whatever. Having to individually select jump for each character, especially when you have 4 extra creatures in your party is really annoying. Especially when I need to keep rearranging the group that's already jumped over to make room for the next one. If the group is chained together, have them auto-jump like Us does right at the beginning. If they don't have the ability to jump that far, fine, their stuck and you have to figure something else out.
