Developing Issue with latest update- HUGE PROBLEMS

As a coordinator of an academic research wich is ongoing since 2 years, my team has developed a code to measure the quality of path based on Mapillary image segmentation. I have huge problems because I am finalizing a research work and the machine learning engine is not responding on all the image that I have loaded before update. Some images are missing, some are not yet updated. How can I solve it? Which is the current limitation of previous API?
