If the name/guid of an unlocked item in the feed is using the old GUID-format (ID_PWNAME*), it will not currently be resolved due to the correlating Map not accounting for that format too, as ID_P_WNAME-prefixed items still have an appropriate GUID, but it's just not used.
The solution would be to either:
a) Add the ID_P_WNAME-tags to the Map and get some redundancy
b) Try to find an alternate way to get the requested (standardised) GUID via the original data (on-the-fly)
