Containers makes preview not load?

So I'm still working on a towerdefense game. now I didn't want my towers to rotate. So I decided to make an invisible turret using the turret behaviour on top of the tower sprite.

Now I just ran into the issue of how to destroy said turret when destroying the tower. A quick search led me to using containers. But as soon as I made a container of a tower sprite and a turret with the behaviour the preview stopped working.

So am I doing containers wrong, or is this a bug?

if so, does anyone have a workaround?

It might be a bug, but it's hard to tell from such little information. What do you mean by "preview stopped working"? It's always helpful to post your actual project file.

Ashley it seems to load everything in when I debug. but that it, program wont run a single line. screen is black.

as soon as I take the turret out of the container it runs like normal again.

due to other reasons I can't share the project publicly.
