50G 7.4.9 - MTU Issues?

[banave]

I plugged my new 50G in before going away for a week. Everything seemed fine in the 24 hours prior to me leaving. When I got back, it seems there are issues, and I notice about 12 hours ago, I was upgraded to 7.4.9 from 7.4.8. It's like there is an MTU mismatch, but I have my WAN set to DHCP and it's auto selected 1500, so I think that looks fine.

Are there any other issues that might cause packet loss or intermittent internet issues, esp on wireless devices (connected to the Fortigate by TPLINK AP's).

Sorry, it's a bit vague, this is definitely new behaviour since either the switch to the 50G from my 60F (brand new install) or since the deployment of 7.4.9 by Fortinet.
