Photon Networking - QueueIncomingReliableWarning

Okay, honestly, I've been having this error probably since the first day I implemented the rather "famous" PUN plugin into Unity, normally when I am testing it's fine, because I either play alone or all the players connect at the same time. But there's the breaking point, when a player connects after some time (I guess when the Queue from all the networking piles up) the player is not spawned and cannot receive any network-related things (chat, other players, mobs, etc.)

The error looks like this:

 Received unknown status code: QueueIncomingReliableWarning
 UnityEngine.Debug:LogError(Object)
 PhotonHandler:DebugReturn(DebugLevel, String) (at Assets/_Plugins/PhotonNetwork/PhotonHandler.cs:170)
 NetworkingPeer:DebugReturn(DebugLevel, String) (at Assets/_Plugins/PhotonNetwork/NetworkingPeer.cs:802)
 NetworkingPeer:OnStatusChanged(StatusCode) (at Assets/_Plugins/PhotonNetwork/NetworkingPeer.cs:1330)
 ExitGames.Client.Photon.EnetPeer:QueueIncomingCommand(NCommand)

 ExitGames.Client.Photon.EnetPeer:DispatchIncomingCommands()
 ExitGames.Client.Photon.PhotonPeer:DispatchIncomingCommands()
 PhotonHandler:Update() (at Assets/_Plugins/PhotonNetwork/PhotonHandler.cs:76)

and I couldn't find any method to fix the error properly with Google so please, if one of you has experience with the Photon Networking pluging for Unity, please take some time to help me out, because I am not really fond of all the networking stuff and this error drives me crazy :I

(in case you need more information/code segments just tell me and I will post them here)

Thanks for help in advance! :3
