Pagination not working with stop_on/stop_before

Hi,

I’m having a little trouble with our events calendar and EE pagination & Switchee.

Default page which shows the latest 12 events with pagination at the bottom. Two additional pages, 2015 & 2016 which shows events from the selected year.

So, when I’m on the main page (events) and I pagination through (events/P12) it works as expected.

When I select 2015 (events/2015) everything works as expected. Paginating through the selected year and the exp loop returns nothing (events/2015/P12) however, in theory this is the exact same page as (events/P12) as it’s showing events by date and these are the latest… so I’ve moved the page into a embed and having the same template called at (events/P12) & (events/2015/P12) yet it doesn’t work when selecting the year but works fine without the year.

I thought it may have something to do with a conditional based on the segment or a parameter in the exp loop, I stripped everything down to the bare bones and still I’m having no luck.

My exp loop is as follows

{exp:channel:entries 
    channel="events" 
    show_future_entries="yes" 
    orderby="date" 
    sort="asc" 
    disable="comments|member_data|trackbacks" 
    limit="12"
    stop_before="2015-12-31 23:59" 
    dynamic="yes"
    status="NOT closed"
}

The segment conditionals are laid out like this (wrote in shorthand to save space)

{segment 3}
    {case = pagination}
        {segment 2 case = 2015}
        {segment 2 case = 2016}
    {case = (NULL)}
        {segment 2 case = (NULL)}
        {segment 2 case = Pagination}
        {segment 2 case = 2015}
        {segment 2 case = 2016}

Am I over looking something?

Thanks for your help.
