I have been fixing this one bug for whole week

I have been fixing this one bug for whole week. At first it looked like a typical "fix it in 5 seconds thing", so I ignored it for a while. It made an error message appear on screen before the start of a level about collisions not being made for a physics object. It is such a minor thing for testers, they just tell me that, close it, and play the game. But it got so horrible that I could not ignore it. It completely ruined the vibe of the game. Something had to be done... I really tried to fix it. But no matter what I did it did not go away. The object that needed fixing was the level tile map that is 12800 pixels wide and 7700 pixels long. The error did not specify where exactly was the problem. I rewrote around 3000 lines of code, changed the in-game physics engine, I had to double check every tile in the level for every parameter. I was really angry. Nothing worked. I wanted to abandon the project, because it made me so mad. I invested so much time and energy into it that I just gave up. Turns out one tile on the map had some kind of anomalous behavior, and after replacing it everything went back to normal. I'm so happy and relieved now, but I also feel extreme burnout from this project. I will still work on it for some time, but for now I need top rest for a couple of days from all this crazy stuff. Anyway thank you for reading this far, I just had to get it out. More updates coming soon, maybe even a new project parallel to this one. Follow for more updates and thanks for your attention
