[UNET] MethodAccessException SerializeItem in Unity.GeneratedNetworkCode

Hi,

I've got the following error when my SyncListBuffs.cs file is located in a different directory than the file that uses it. If I put them in one directory, everything works well. (Unity 5.3.2 f1)

How could I walk-around this issue?
Should I report it as a bug to Unity?
Should I submit a but to bitbucket unity\networking?
