Crash iPad pro 12.9-inch

[assembleMHN]

When scrolling backwards in time i get a crash on the ipad pro 12.9 inch simulator with OS 11.4, an exception breakpoint stops at this specific line of code:

UICollectionViewLayoutAttributes *toAttrs = [cvLayout layoutAttributesForItemAtIndexPath:[NSIndexPath indexPathForItem:0 inSection:toSection]];

It seems to happen when hitting a date cell at the same time as scrolling. i have not been able to validate if this only happens on the sim as i do not own a ipad pro myself.

Stacktrace:
