I opened your project and tried adding two cylinder (all flavors of cylinders) and can not reproduce the traceback. How exactly did you trigger the traceback? Do other projects work?

Thanks for your reply! The error disappeared in a new case. This error may have been triggered by accident and the exact cause is not clear.

If you do reproduce it, try to remember and tell me exactly what you did so I can fix it.

ok, I will keep you informed if this error occurs again.
