Custom script code disappeared

Custom script code disappeared

I was working on the following function udf_generateids.convert_numeric_to_alphanumeric_code and when I opened the function, it ended up seeing 

string udf_generateids.convert_numeric_to_alphanumeric_code_896426000014261704(int value, int digits, string code)
{
}

My code disappeared. I never created a function with the name convert_numeric_to_alphanumeric_code_896426000014261704 with the random number. The other big issue is that all my script logic has disappeared. There is nothing in the version either.

I only created the function today so I don't have a previous back up.

Can you please investigate why this happened?

This is somewhat related to a previousI issue (https://help.zoho.com/portal/en/community/topic/deleting-fields-from-forms) where a function that I previous deleted  called udf_product.get_product_service_id but there were references I never created with the random number linked to my code
1. udf_product.get_product_service_id_896426000011845953()
2. udf_product.get_product_service_id_896426000012564478()
