I am currently working on a Conways game of life clone. Now while the project starts correctly, meaning i get a window that opens, the window closes after around a second. My Visual Studio debugger then informs me of a stack overflow, since i want to know what happens and where it happens, look at my main threads callstack, which tells me that it consists (as far as it is showing me) only of "sfml-graphics-2.dll!00007ffc917be63e()" The thing is i am probably intermediate in c++ and a absolute noob with sfml, but i have a feeling that there is some infinite recursion in the dll. If the reason of the error is with me, please inform me of a fix.
I have attached the 3 currently existing c++ files. If the headers are needed as well or any questions to my code arise, please ask.
Thanks for any help in advance.
