pfSense

tested versions:
2.4.5
2.6.0

Prereqs
Admin A logs in to Firewall
Admin B logs in to same Firewall

Intention
Admin A would like to create a firewall rule
Admin B would like to create a separator

Issue
If the two admins execute the changes at the same time, under certain conditions existing firewall rules will be deleted!

Steps to reproduce
- Admin A creates one additional firewall rule. (Admin A does NOT yet click on apply.) The rule is now visible at the top of the list.
- Admin B creates one separator. The separator is now visible at the bottom of the list.
- Admin B clicks "save" on his separator.
- Result: The firewall rule in the bottom position is deleted and is replaced by the new firewall rule.

Notice:
I have already created a forum post on https://forum.netgate.com/topic/171774/rule-disappears-when-multiple-admins-edit-rules-and-separators. We think it is worth mentioning and improving
