create clone of [ Myself]

This clone block is glitchy today and yesterday.. My game was working.. then today, its not cloning half of my stuff… If I edit anything on a certain sprite, I guess the new clone code kicks in and breaks that sprite… So.. for now I will have to not work on my project, but I wonder why this bug is happening… So So Scratch Team, if you see this.. please let me know whats happening with clones Thanks

Clones works for me. It could also be layering that is the issue. If you use backgrounds sprites the clone could be behind it instead of in front. Good debug test is to remove script for background and see if clones show up. Second known issue: you unintentionally used a forever loop and are creating more than 300 clones with out deleting clones. When that happens cloning will behave unpredictably.

I have this problem a lot, where clones don't work. Try saving the project, and then refresh the page, and it might go back to normal. If that doesn't work, then I don't know what's going on, sorry

For future reference, I just wanted to say that I haven't been experiencing this issue the way OP describes. Of course, that does not mean that the problem doesn't exist.

Clones can be tricky. Like @Gilstylin alluded to, weird things can happen if clones are not cleaned up properly, and a lot of them accumulate.

One thing to try out (and actually, to try and always do when working with clones) is remembering to `Delete this clone` when it is no longer needed. If the project is complicated and has many sprites and clones, I think it will also be a good idea to broadcast a `Clone Cleanup` message in between stages, and have the receivers of the message simply `Delete this clone`.
