When converting a station from R2 v522 to v535 getting error: "Link is not valid: Link invalid for unknown reason".
TAC I/A Series
R2 UNC and WPP
The v535 LonExtras jar is not correctly handling converting links that reference SNVT type FlexSnvtTempSetpts.
Download and Install the v532a LonExtras jars in WPP. Convert the station successfully then install v532a lonExtras jar and the station in the UNC.
