I'm having trouble finding Aloth. I don't know if it's a technical issue or if it is supposed to be like that. I read several guides and they say Aloth should have been at the Engwithan Digsite. I already finished that quest. He wasn't there and I didn't get any dialogue to recruit him. What do I do wrong? I already lost Eder in the first chapter so I'm short on companions. I need him.
