Hello, Finleydesign,
Thank you for your response.
We would like to inquire about the reason why your child theme is experiencing periodic changes? We assure you that we are not influencing it.
We are trying to explain that if you have uploaded a file that works in the child theme and everything is fine, then there is no need to worry about it anymore. However, if someone in your child theme is overwriting/deleting that file, then it is a matter for you to resolve. You will need to deal with this and in principle, there will be nothing required from us.
Kind Regards,
8theme team
