Abyss multiple bugs

I will post this as a new, because earlier abyss reports remained unanswered and unfixed

Firstly, generally on Dunes, but experienced on one other map too, using abyss craft, having an abyss scarab, still having only one or two abysses instead of 4-5.

Another issue is that on every third map, there are abysses, which are not closed, remain open and spawn ghost abyss monsters forever, really annoying.

Third problem, after running 100+ abyss maps, I realized, that generally only 1 or 2 abysses (with hoards) are going for long with several major trenches, but the rest 2-3 abysses are just short ones with some hoards and only 1 major trench...

why is this? it seems intentional based on the pattern I see. They should be almost the same length

Also it would be great to not be able to open a new abyss, while one is in progress or at least have a confirmation, because a lot of times, a lot of abysses goes to waste just because accidentally opening them, mainly on narrow maps

Additionally it would be great to see all abysses (and as a matter of fact all rituals on a map), it's extremely annoying having to search for them for ages on a cleared map...

First two bugs have been in the game for many years now and might as well be 'features'. Same for #4. Was an issue back in Affliction, and I imagine every single league where Abyss has been relevant since its' release.
