Gearen Attack and Sp. Attack EV training rooms have weird cave field on them, don't know if it's actually a bug: http://puu.sh/mSWyQ/af7ae43009.png
Also, on attack EV room, i guess Beedrill should be removed because of its 1 Sp. Defense EV, and those pokémons should have only the Attack EV, that's just a suggestion actually.
