...that you can only page to 99 pages in the Filter? Say you pick Bounty Hunt - All - Newest with the intention of finding out what the very first map was (there isn't an 'oldest' so that's not an option) and you keep paging right then you'll be disappointed to find it won't go past page 99 and as new ones are added the oldest disappears off the end.
I guess if you searched on A-Z you'd see them all (though maybe I don't know for sure as I haven't tried it). It's a bit annoying as I was hoping to see the earliest ones and was also hoping that pressing left would've wrapped you back round to the first, but no such luck.
Ah well, another thing to consider Mr Ubisoft, if you happen to be reading this.
Okay, so this morning I tried 'All Solo & Co-op', 'ALL', 'A-Z' and once again it stops at 99 pages. Which believe it or not doesn't even get past the 'A's. Something of a failing I would say. I think they severely underestimated the requirement. A 99 page limit doesn't even come close, a 999 pages might be nearer the mark, but even that might not cover all the maps now available. So buck up Mr Ubisoft!
Okay, a bit more digging about and it seems that the 99 limit is only for consoles. Quite why the PS4 and XB (I assume as I don't have one) can't page up to the same limits as the PC can (though again I'm only assuming as I don't have a PC version of the game) but on the web you can page all the way to page 263 (at the moment) when, say, looking at all the Bounty Hunt maps. And what's worse is the PS4 only shows 15 maps a page, the web shows 20 maps a page.
And if you're sitting down - the total number of all maps (up to mid-day UK time 30th July 2018) is 59,228 maps, spread over 2,962 pages of 20 at a time.
So, just shy of 60,000 maps to play. That should keep us all busy for a while, I'd say.
EDIT:
It seems that figure includes all maps and all types both Solo and Multiplayer. Excluding Multiplayer the total number of maps drops to 35,553.
It's still of lot of maps.Interestingly that shows that Solo maps run about 60% compared to Multiplayer being about 40% of the total.
