Pete will always deliver and by default the dlc data for the item is copied first by DiiLC application. Wendell will not deliver if that specific player/character has been played in the same day (but you could just move the Wii date one day ahead prior to running the game)
You may want to check whether you reinstall back the same RVFOREST.DAT file from that WIISAVES/RUUP folder in the SD card by using Waninkoko's savegame installer application.
