v6.43.4 + v6.43.7 corrupts the use of Address Lists

Same issue: http://forum.mikrotik.com/t/address-lists-in-firewal-rules/125553/1

Create supout and send to support to get it fixed in upcoming releases.

Do you mean that you have addresses in the list but rules that use address list are not working? Can you provide an example? Address lists and firewall have not been touched for a long time. Also we have not seen such reports in support. Are you sure that simply other firewall rules are not matching this traffic before it reaches this particular rule that uses address list?

Seems like a perfectly reasonable rule ( I like it because its port forwarded limited to white list members).
However have you made any other changes lately to your setup?
Without seeing the whole config, sometimes its harder to pinpoint the issue.
