Router crashes with if(dupe(dupid)) return log.debug('dropping duplicate');

[Zeipt]

Trying to connect two peers

1. I start th-router from .bin folder.
   
2. Save "link" from its output into links.json file:
   [
   "link://192.168.0.100:42424?cs1a=aot5jpsln6cladvzaljdaanined72uxzom&cs2a=gcbacirqbudaskugjcdpodibaeaqkaadqiaq6abqqiaquaucaeaqbkml5k6356vowblycjv6dczqswejtbj7h6psfnerp6j3xkqvybka7fxw2k7njlob7pygamxztwyjatcigyzogp2hpvulaj3drpn7lpnsmbndqdya2xiguighswttv5y4avqelnjo7mkniihz37mylyjc7s5upoz4a2ygwq2hz2iz7k7pro7fxx3pyizyqw2o2zpfg7qf3h4h4ttm45sxp7z42qzal5ftunkhubgol2no7bigvaoqr4i5ojbxuhfnptojryfkqldmbllfe67bjvaihxlf6gvfzzpi7hewjeewns5ctycp4amykuqtmql73qdnabtsw6lxz55snbvfs7gebyb7rmcwclhnnozjk3bkiq52u2flcq7iom4ay4s2jc4swjyaclnzsuu42igayrqlbaicamaqaai&cs3a=x2w6lnsjbehbjbirgjirwcuppgjyw6xcsf7savyl7ffrwhcv3f2a"
   ]

I have this peer as "first":

var th = require("telehash");
var path=require("path");

th.generate(function(err, endpoint){
    if(err) return console.log("endpoint generation failed",err);
    // endpoint contains a `keys:{}`, `secrets:{}`, and `hashname:"..."`
    var id = endpoint;
    console.log("id", id.hashname);
    var mesh = th.mesh({id: id, links:path.resolve(__dirname, "./links.json")}, function(err, mesh){
          if(err) return console.log("mesh failed to initialize",err);
          // use mesh.* now
            console.log("mesh initialized");
        var routerlink = mesh.link("link://192.168.0.100:42424?cs1a=aot5jpsln6cladvzaljdaanined72uxzom&cs2a=gcbacirqbudaskugjcdpodibaeaqkaadqiaq6abqqiaquaucaeaqbkml5k6356vowblycjv6dczqswejtbj7h6psfnerp6j3xkqvybka7fxw2k7njlob7pygamxztwyjatcigyzogp2hpvulaj3drpn7lpnsmbndqdya2xiguighswttv5y4avqelnjo7mkniihz37mylyjc7s5upoz4a2ygwq2hz2iz7k7pro7fxx3pyizyqw2o2zpfg7qf3h4h4ttm45sxp7z42qzal5ftunkhubgol2no7bigvaoqr4i5ojbxuhfnptojryfkqldmbllfe67bjvaihxlf6gvfzzpi7hewjeewns5ctycp4amykuqtmql73qdnabtsw6lxz55snbvfs7gebyb7rmcwclhnnozjk3bkiq52u2flcq7iom4ay4s2jc4swjyaclnzsuu42igayrqlbaicamaqaai&cs3a=x2w6lnsjbehbjbirgjirwcuppgjyw6xcsf7savyl7ffrwhcv3f2a");
        mesh.router(routerlink);
        console.log(mesh.uri());
    });

    mesh.accept = function(from){
        console.log("accept from ",from);
        mesh.link(from);
    };
});

Start it:

and second (here I'm trying to connect to first peer)

    var id = endpoint;
    console.log("id", id.hashname);
    var mesh = th.mesh({id: id, links:path.resolve(__dirname, "./links.json")}, function(err, mesh){
        if(err) return console.log("mesh failed to initialize",err);
        // use mesh.* now
        console.log("mesh initialized");
         //console.log(mesh);
        var routerlink = mesh.link("link://192.168.0.100:42424?cs1a=aot5jpsln6cladvzaljdaanined72uxzom&cs2a=gcbacirqbudaskugjcdpodibaeaqkaadqiaq6abqqiaquaucaeaqbkml5k6356vowblycjv6dczqswejtbj7h6psfnerp6j3xkqvybka7fxw2k7njlob7pygamxztwyjatcigyzogp2hpvulaj3drpn7lpnsmbndqdya2xiguighswttv5y4avqelnjo7mkniihz37mylyjc7s5upoz4a2ygwq2hz2iz7k7pro7fxx3pyizyqw2o2zpfg7qf3h4h4ttm45sxp7z42qzal5ftunkhubgol2no7bigvaoqr4i5ojbxuhfnptojryfkqldmbllfe67bjvaihxlf6gvfzzpi7hewjeewns5ctycp4amykuqtmql73qdnabtsw6lxz55snbvfs7gebyb7rmcwclhnnozjk3bkiq52u2flcq7iom4ay4s2jc4swjyaclnzsuu42igayrqlbaicamaqaai&cs3a=x2w6lnsjbehbjbirgjirwcuppgjyw6xcsf7savyl7ffrwhcv3f2a");
