Hi, almost always, objects created by a spawn are created twice.
I use an external layout (loaded at the beginning of the scene), but the objects are created later. I discovered that this bug was found years ago.
I am using version 5.4.205, for Windows 10 64-bit.

🐛 bug
Clicking on the preview button while editing an external layout loads its object… s twice on the scene, according to the debugger.
Preview started from the scene tab or the events tab:

Preview started from the external layout tab:

Confirmed on GDevelop 5 b114, Windows 10 64-bit
I don’t believe this is a bug. If you preview the project and the external layout tab has the focus then it previews that tab for some reason. You can set the default scene.
Thank you, it seems to be working now. I will do more tests.
