I a long time indexer and started this week I added the US-City Directories, 1902-1935 ( part B). The one I started yesterday is far beyond the 250 entries. It has a possible of over a thousand entries.
Here is the batch info: MQN3-N7Y and https://www.familysearch.org/indexing/batch/d80424db-70db-49ae-a03c-285411a132a2
If this image could be divided at least half it would be less difficult and less problems with errors.
FS does not, and probably will not, divide batches. If this batch is problematic for you, you can always return it.
