I found a bug in my game and made a minimal example of it. You can find the zipped project at this link: Gdevelop bug, firebullets out of camera frame.zip - Google Drive
The problem is as follows. This is what the scene looks like:
The dinosaurs ‘Percy’ fire bullets towards the player. The player has the smooth camera behaviour. As long as the player stays within the initial camera frame, all is good. But as soon as the player walks outside of the initial camera frame, then all the bullets dissapear at the same time.
this bug occurs as well on the online editor as on my Windows 11.
