Same here. While testing my game I figured out that the hero can only pick up items, which are activated for adding them to the inventory. This is a different behavior from before the last update and makes mini games impossible, in which items are only used as symbols but not as consumable items.
I also placed some new items for testing this bug. This definitively has something to do with the “Add to inventory”-property. If this property is deactivated the hero is unable to pick up the item.
