wg output:

while routing tables shows

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         169.254.1.1     0.0.0.0         UG    0      0        0 eth0

in this case, 10.70.0.14 was removed, and a new node 10.70.0.12 joined.

upon restart, wg shows the same, while routing table correctly shows

10.70.0.9       0.0.0.0         255.255.255.255 UH    0      0        0 nm-foo
10.70.0.12      0.0.0.0         255.255.255.255 UH    0      0        0 nm-foo

This is running within a kubernetes cluster, w/ userspace wireguard-go, and using the gravitl/netmaker:v0.9.4-kube image, if that makes a difference.

Routes have been refactored in v0.11.0, so this should no longer be an issue in the newer version.
