Agreed - the 184.108.40.206 trainer is now completely nonfunctional.Grim Dawn had a small update today. No notes that I have found detailing the changes. Now the trainer makes a "boop" sound when you try to activate it, and nothing changes. Prior to this patch, I found the trainer most helpful. Thank you.
Correction, the changelog is now visible. Major changes to the Loot Filter and general rebalancing affecting items/devotions/skills.
