Hi!
I understand that you need to fix a bug with the input fields in your Unity project. The problem might be caused from few possible scenarios and I have to see the code to know which one it is. I am currently specializing in game technology and I have done few completely independent game projects. As they have been fully independent, I have made everything from graphics to coding myself, using no other assets.
My plan would be to locate the faulty code (or other cause for the problem), fix it and add the functionality you wished. All the steps will be documented properly and sent to you with the fixed product. I don't think this task will take too much time, unless it is caused by some bigger problem in the code or bug in Unity itself.
Feel free to contact me at any time!
