Build error on Fedora 38 with gcc 13

[ycollet]

I am trying to build grainbow on Fedora 38 with gcc 13.
I met the following error during compilation:

I can reproduce it with gcc 11.3 on Ubuntu 22.04

Can look into a fix

[ycollet]

Thanks a lot for your work first and for this fast answer ! :)

[sjfricke]

short answer, I realized the AttachedComponent is completely unused, not sure what this was left over from...after removing it I was able to build and see it working as normal with that

[ycollet]

Thanks, I will try that on my side.

[ycollet]

Yes, it worked on my side. Thanks
