Block Combinations Draggable / Slider stops where it shouldn't?

Nope, I don't think so when the game is running (never updated) but uses the latest version of OS or some bugs will happen because of Latest OS since Upgrading the Os will not change apk files or in-game script (Apk game engine are written on some other language)

Yes, This bug is happening in-game!

That's a valid point or a good assumption why this bug is happening in-game

I think when a single slider is placed on a rail it covers all up and down of the rail

When slider moved up once:
It redraws the slider, the slider position is changed and the rail will show downwards (To let slider move back here again)

When slider moved down once
vice-versa!

To move the slider up or downwards

When 2 sliders are placed they will still cover all rails but i think the redraws or the algorithm that reads position or calculate position will bug out because!

In this card:
The Upper slider will cover all rails but you can position it as you want (But it only re-draw the slider rail position for itself not for other sliders)

The lower slider will cover all rails too but cannot go upwards (Since the rail up is re-drawed for the 1st slider upper slider and for 2nd slider) There will be a limit since there's no slider for the 2nd slider (it will limit to that position it redraws)

This bug will happen because of the algorithm that calculates or read positions of sliders and move them back here or there

But you can avoid these bugs like this

To Do:
1st slider is placed on the same rail where 2nd rail cannot be positioned
2nd slider is placed on the same rail where 1st rail cannot be positioned

Both read and cover all rails the algorithm after moving them will redraw the slider rail perfectly!
but many sliders draggable on same rail you'll face difficulty or you cannot fix them unless you block them or limit them to some point!

Card (NO BUG):

 

Yes, maybe but I saw some bugs device to device happening around the game but there's no right thing I can say about OS and games anymore then because I tried to search to I cannot find anything OS and games related thing and I think It should work fine (If the certain requirement is met when downloading games like this Mekorama is available for phones and tablets with iOS 6.0 or Android 2.3.3 or higher than this) Maybe IDK.

I don't see the more or like the same bug here since there are not like on the same slider but the slider is getting attached with the first slider but mekorama isn't designed to have dual slider vertically and horizontally on the same rail. So you can do or avoid the attaching like this!

But maybe I'm wrong but I don't understand your card and what you wanted to achieve So I can be wrong and what I understood is 2nd slider is not covering the rail since 1st slider is covering is own Top rail but also the side rail is attached with the slider itself 2nd slider can move if the slider is on the place but it's out of rail once the upper slider is moved and the 2nd slider is on its place (Then 2nd slider is an FD)

Card ( Not sure you're trying to achieve what):

 

@D.S.Masters not sure what are you trying to achieve in the last card!

 

I played on emulator too yes the thing about emulator is right sometimes it just glitches or bugs out! Or not stable at all on emulator too!

Yes. Mekorama has a lot of bugs and more discovering..!

 

Yes, Many things are getting discover (I just discovered a floating ball trick a few times ago) and more to discover!. Also, these tricks or bugs somehow add new concepts into the game and give you a new idea to think over and create a level based on that if it is stable enough! and the players which play your level will be surprised by such a new concept and will be shocked to see new things. i still have some bugs but not that stable and if i made them stable then I'll create levels with that
