Unbound refuses connections when network mask broadened

[Froggersson]

I broadened network mask from /24 to /23 on one network. When using ips from the new block Unbound refuses to give answers to queries. Unbound allowlist has the new /23 in its rules, but its not working. As a workaroud I made a new network /24 manually (the new block) and after that queries work normally. Also the original /24 works even though it is /23 in the list. Is this a bug or something?
