When you have a large number of chests, the chest list scrolls inconsistently and strangely.

Reported via 2016-10-20 Nexus Mods bug:

as in the title the scroll of the mouse its very... i don't know how to explain it very "nonsensitive" sometimes its like i just touch the scroll on the mouse and it goes all the way down (never up) many times i cant scroll until i switch to another chest ( sometimes i have to do it many times), that's when i have luck. BUT most of the time what happens is i open the scrolldown and it goes all the way down and can't scroll up.
[...]
[...] its like the dropdown/list of chests has a very long delay between me scrolling up or down and the mod receiving it. Also a problem that i realized its that when you scroll VERY slow it seems to work better but scrolling like normal or a little "fast" it doesn't respond most of the time. im thinking that its probably that i have like 61 chest in the same category because i haven't organized it yet in that farm when i organized them in the other farm it works perfectly fine with not having to scroll.
