Location Game tile texturing

I have the below code as a GPS controller and in Unity my map tiles are texturing fine... however, when I run in Xcode I get red question marks on all tiles. Is there something I'm not seeing here?
Have checked in Xcode debugger and my location coordinates are being found correctly but just not showing on tiles
Many thanks

Trying to figure out how to pause and resume in Cocossharp (BouncyGame)

So I'm playing around with the BouncyGame. I made it so that when you start the game you need to press the screen for it to start. I would like to implement this whenever you play a new round as well. I tried to reuse this att the bottom of my code but it made it extremely laggy.
// Register for touch events
var touchListener = new CCEventListenerTouchAllAtOnce();
touchListener.OnTouchesEnded = OnTouchesEnded;
touchListener.OnTouchesMoved = OnTouchesEnded;
AddEventListener(touchListener, this);
}
void OnTouchesEnded(List<CCTouch> touches, CCEvent touchEvent)
{
if (touches.Count > 0)
{
Schedule(RunGameLogic);
scoreLabel.Text = "Score: 0";
paddleSprite.RunAction(new CCMoveTo(.1f, new CCPoint(touches[0].Location.X, paddleSprite.PositionY)));
}
}
I have no idea how to do this, tried for 2 hours with 0 results. Any suggestions are welcome.
Here's the full code.

Thanks in advance!

Figured it out!
There is an "Unschedule" Method built into Cocossharp.
Ref. https://developer.xamarin.com/api/namespace/CocosSharp/
I just added
Unschedule(RunGameLogic);
at the very en of my RunGameLogic method under
if (ballSprite.PositionY < VisibleBoundsWorldspace.MinY)
So once the ballSprite is out of bounds it will Unschedule what i Scheduled in my OntouchesEnded method. That means the code goes back to listening for touches.
Might have made some errors, but this is as best I could figure it out and it works!

CS1061 error Xamarin/Visual Studio

I am very new to Xamarin & app development and I just wanted to run this because it is a very similar project to one that I am creating.
Thanks for your help

SetImage is a extension method contained in Xamarin.SDWebImage. Ensure, that you have restored all nuget packages or have installed it via
Install-Package Xamarin.SDWebImage
see: https://www.nuget.org/packages/Xamarin.SDWebImage/

Here a explanation of the error.

CS1061 - UIImageView does not contain a definition for 'SetImage' and no extension method 'SetImage' accepting a first argument of type 'UIImageView' could be found (are you missing a using directive or an assembly reference?)
In your code I don't watch a declaration of ImagePhoto check right click goto definition. And verify that for imagePhoto exist a method setImage ImagePhoto I'm asumming that is object of type UIImage
ImagePhoto.SetImage(
url: new NSUrl(Gravatar.GetURL(TextEmail.Text, 172)),

How to lower the terrain using OpenSimulator?

I made a simulation in OpenSimulator. I changed the terrain to resemble that of Atlantis and used the OpenSimTide module to have the tide cause the disappearance of Atlantis.
Now the OpenSimTide module works, but for some reason I just can't find out how I make the terrain go lower whenever the tide reaches a specific level. How can I achieve this?

Unity System.Drawing Internal Buffer Overflow Exception

Goal
Get a gif working in unity from a URL, I am currently using the WWW class. I am currently getting a byte[] and converting it to a System.Drawing.Image. This works in the editor but not any build
Error:
"Type Load Exception: Could not load type" System.IO.InternalBufferOverflowException from the assembly "System.Drawing.Image" at line 111
Why?
It has to do with the System.Drawing.Image.FromStream built in method, Unity for some reason doesn't like it. The other options are .FromFile and .FromHBitMap, I dont know how to use HBitMap but going back to my original plan, .FromFile is unusable to me.

Thoughts
byteArrayIn.GetLongLength(0)
returns 80,000 at most.
The last debug statement coming through is Called Image Loading BACK.
I will write my own fire streamer if necessary, and if it is necessary can someone point me in the write direction for that.
I think the main workaround is dealing with the Image.FromStream().
There are two of these in the scene.
All thoughts or solutions are welcome, I really just wish I knew how to tackle this error so that I could share it more with the Unity Community.

We faced the same problem this morning.
The app is not finding a type in the System.IO namespace required by System.Drawing.Image.
The missing type has apparently been stripped from the system.dll that is packed during the build process.
To fix this, you need to copy and replace the unity generated System.dll with the original mono System.dll.
In your build, replace projectName_Data\Managed\System.dll with the System.dll found in Unity's mono installation folder:
Editor\Data\Mono\lib\mono\2.0 (relative to the root of the Unity installation folder).
Hope it helps!
