7.18 breaks Wireguard?

Hello, I just upgraded my RB952Ui-5ac2nD from 7.16.2 to 7.18. I had configured the device as a Wireguard client to remotely manage it, however the tunnel no longer comes up despite no configuration having changed. When I roll back to 7.16.2 the tunnel comes back up immediately.

Is this a known bug? Please let me know if there is any diagnostic output I can provide to aid in diagnosing the issue.

Provide your 7.18 config
/export file=anynamyouwish ( minus router serial number, any public WANIP information, keys )

I had windows file shares working before the upgrade, my win 8 PC at 192.168.100.53 had a drive mapped to a win 7 PC at 192.168.200.60 through wireguard.
I can ping most PCs at 192.168.100.0/24 from 192.168.200.60 and VNC works. I cannot ping any 200 network PCs from the 100 network.
It does not make sense the hAP ac would affect this but I noticed this after the upgrade. I am comparing firewall rules in both MTs to see what I might have goofed up.

I had problems since I switched to wireguard with drive mappings but got it working after changing windows firewall rules based on this info.

I upgraded to 7.18 again to provide the configuration file, and Wireguard is now working fine, go figure! Sorry for the false alarm everyone.

Nope often a simple reboot fixes things, nothing magical.
