Thank you for the report! I'll see to fix those!
Some of the dialogues aren't updated really. Like the brothers, they are in reference to the free scene you can always get (the interactive one).
Scotty is hidden outside the store. You can see him jumping near a tree on the left side.
Emma should have a new dialogue if you finished the quest and give Ramdo all the materials.
This might be interferences from the old save. I know that the search light quest is a bug from older saves. It won't happen if you start from the beginning. Unfortunately, that's a limitation of the system that I'll try to fix.
2 Erics is too much, lol! 3 even more! Hahaha! But don't worry, they shouldn't interfere with the results of the quests (I hope).
I'll fix everything that I can. Thank you very much for playing and reporting!
(Also, let me know if you used an older save, and if the save was from Chapter 2 or Chapter 1, cuz they can really affect the new chapter).
