Thanks to the reporter and zzz.
Caused by router.tunnelBacklog not being a 'required' stat (always generated). Any router without full stats enabled would therefore NPE when checking if ff-eligible.

<+dg> zzz: I can bandaid but I can't reproduce it. Is it possible that CoalesceStatsEvent (SimpleTimer.TimedEvent) isn't working properly? RN was seeing stats issues so that's why I asked
<&zzz> dg, i suspect you can reproduce it with stat.full=false ;)
<feed> [ I2P ] fix on non-full stats routers (thx zzz)
