super grok image generation limits

The image generation limits via chat has reduced significantly over the last 24-48 hrs and in the last week or so it resets 24hrs later rather than 12 hrs. I could only generate about 20 images this morning. Usually closer 60 to 80ish. Last night it was glitching and wouldn't even try to create any risky images. They must have changed something overnight. This is for image generations via chat.
