Routes disappearing on their own

Hey Guys, We have a controller that POST route configuration to endpoint: “http://api-gateway-admin:8001/routes” , but after some time some of the routes registered magically disappear. Lets say routes 1-12 were registered after a day or so it will only have 8 routes registered, 4 would have fell off somehow. We are using Kong v.2.0.4. Any ideas?
