you can/should report a bug... there are also some helpful hotplug examples on the forum that you could use to compare that the ip has not changed and skip the reload... (as an interim workaround)
Just because it hasn’t been suggested, how about making a backup and then resetting to defaults. See if the behavior occurs on a fresh config. Then install any additional packages (one at a time, except for dependencies of course) and see if you can pinpoint when the problem first manifests.
It seems like this could trigger if the leasetime is different on the renewal (run ifstatus wan and look at the data section). I saw this same behavior today when my lease renewed, but mine renews every 2+ days.
