I raised an issue on github which was closed, and issues seem to have been disabled on github now so I can't respond there.
59e556f on wireguard-go breaks Wireguard working over OpenVPN on windows. It only ever worked in my private builds as there was no public release of wireguard-windows that included 66ad537 (which fixed a routing problem in wireguard-windows). Now with wireguard-windows 0.1.1 Wireguard over an OpenVPN tunnel no longer works again. I have triaged it with my own private builds of wireguard-windows and 59e556f is where it starts breaking.
