all valid questions there. ^

I would like to express the reason why I lean towards the possibility of memmory bug , the reason is , I have experienced this type of behaviour specifically where changing a function name or adding/removinh code to parts which shouldn't do anything , actually resulted in the application randomly behaving correct and incorrect at other times , I figured out I was removing a pointer and directly after that I was accessing it without checking if its valid , which was just a memmory bug ..
