I was at work using PokeGTS about 4 hours ago and everything went fine, I was browsing on the options to modify a Zubat and an event Riolu. But then I went home and I just haven't been able to access to the modifying options of ANY pokémon but the first 14 (Bulbasaur - Kakuna). The website will correctly display the options from "Select a Category" to the pokémon menu, but if I select ANY pokémon from Beedrill on, the website will just return me to the "Select a Category" screen without displaying any error message. That means, I just can't access the options for any pokémon after Kakuna.
And I tried to receive a Venusaur from PokeGTS, with a TM51 attached. The pokémon I received was almost the same I asked for, except it didn't have the attached item.
What's going on with this bugs or errors? I tried to access the rest of the pokémon from PokeGTS with two different computers, two different browsers, but the website always inexplicably returns me to the "Select a Category" screen without showing me the options to modify the pokémon.
Thanks everyone for your help.
