I keep running into this same issue. Somehow my Pokemon TXT file in the PBS folder decides to magically delete a certain amount of pokemon from the bottom. One time it cut me off at #40 (Yes it only went up to Wigglytuff) now I get errors about my own pokemon not being existent. It stops at Uxie.....I still need all 649 AND they better have that base EXP thing fixed. Last time i downloaded it everyone was 0.
