Hi DrabOwl94
I think that if I understand you correctly you have a Lot of chunks (which translates to a lot of links to small 1MB files, because this is how you setup the chunk size). Now apparently you have reached the maximum number of chunks per specific Dataset version (at the end this meta-data is stored in a document with limited size, specifically 16MB).
How many chunks do you have there?
(In other words what's the size of the entire dataset in MBs)
