[BUG]Duplicated 'max_id' using location_medias_v1_chunk to get posts

[FelixWu1110]

Not sure whether it's a bug, but I found when I use location_medias_v1_chunk to get posts, and after like 20k posts the max_id I got would redirect me to the first page, anyone met this issue before?

The max_id I record
{"max_id": "WyJRVkZEVVdzdGF6TmpRMnhTVTA0MU0waEJWVGQyTTJOa1owdHJTak0wVEhSelFYZGZkMlV0ZDBka1YzRlZTRVJ5WDIxTFNrNUNPRVl3VlVwU05raDFZbDl6TkZkdFFXWktObWhmY0hoTExXWllaa05pZW1ZNU5BPT0iLCAzNDIsIFszNDM4Mzc2NzY1Nzk1NTcwNjA3XV0=", "fetched_count": 21188}
{"max_id": "W251bGwsIDMzNSwgW11d", "fetched_count": 20753}
The second one would redirect me to the first post. Like shown in the following image.

The post I got in the above image. there are too many duplicate posts would be fetched again.

Anyone know why this happens? Thanks for reading.
