Server edition crashes when limited user deleting linked customer

Just reporting an abnormality.
If a restricted user with the correct access to all the required modules creates a customer and then generates a Sales Order for that customer.
The user then attempts to delete the customer, there is no warning that there is a Sales Order associated to that Customer to be deleted and the Manager Server goes off line for all entities (Crash - Browser says site not available?) and comes back after a period.
If a user with full access to the entity does exactly the same as above that user does get the warning like expected and is then forced to first delete the Sales Order associated with the Customer and only then can the customer be deleted as normal. There is no crash.
I suspect a permissions thing?

Fixed in the latest version (20.9.74)
