I can confirm that Alphaman's bug still exists on an A3 1.22b05_beta built from scratch (3 times) with manual configuration changes.
I can consistently cause the Router state to crash preventing any additions to the Access Control - Add Policy panel. Any attempt to add a policy (with any settings) causes the router to crash/reboot and return to the logon page. The changes are not saved. All other configuration pages appear to work fine.
I have not determined what combination of settings (or events) lead to the router state crashing. After flashing the firmware, the Add Policy page works as it should adding or deleting policies; after configuring multiple settings across the router the Add Policy bug appears. Reboots are done whenever requested. Backing off on settings does not fix the problem once it has occurred. (It is still possible to add or delete 'Never' schedule policies)
This is not a priority issue for me to track down, and as such I cannot look into further at this time.
