Cache downloading seems to skip/not download some files in Index 40

Running the cache downloader from scratch seems to download all indices except for some files inside of index 40/js5-40. You can catch this by comparing a full 918 cache downloaded from RSCD to one that was downloaded using this tool. There appears to be (at the time of writing this issue 5/3/2021 : 1:06 A.M. est) 4,961 files not downloaded (about 500/700mb worth of data).
