Issue with Image Generation Tool in Dust Agents Explained

Hi everyone, I encountered a issue using the image generation tool. I created a Dust agent (The Forge), based on GPT 40, which has the image generation tool. I assigned it to another Dust agent (The Mentor, based on Gemini 2.5 Pro) with the Run agent tool. So, The Forge is a child agent of The Mentor. When I ask The Mentor to generate an image, it calls The Forge, but the generated image is not attached to The Mentor's response. You can see in the attached screenshot that The Mentor confirms that the generated image exists and provides the ID, but I can't find the image. Please tell me if I don't know where to find the image, or if this is a bug, or if it's simply not possible to proceed like this. One last detail: when I invoke The Forge directly from the Dust prompt, the generated image is correctly attached to its response. Thank you in advance for your help.
