All 68 of your images were received but only 4 were able to be included in the outputs due to lack of overlap in a treed area.
As noted in the Data collection guidelines that are agreed to at the time of upload, you should be using at least 80% overlap in your data collection to make sure you get enough looks at everything. More complicated scenes, like trees, require more overlap. We can see that your flight used 75% overlap.
We will provide a one-time 50% refund for overlap related issues.
