Reopening a shader causes Append to not output the right format

While modifying that trilinear shader you showed me to support scaling on each axis as well as specular and normal maps, seems closing and reopening the shader and trying to hook the UV coord after the Append causes this error to be spit out:

Type A: VTv2 Type B: VTvPending

UnityEngine.Debug:Log(Object)

ShaderForge.SF_NodeConnection:LinkTo(SF_NodeConnection, LinkingMethod)

ShaderForge.SF_NodeConnection:LinkTo(SF_NodeConnection, LinkingMethod)

Attempt to connect invalid types

Deleting the Append and remaking the node fixes it.
