BUG found- Free For All and land problem

I found that bug that i thought it happens only on cracked version of DOTP 13, but while i tried to play on Free for All doing to AI the Nayan Invasion deck http://www.slightlymagic.net/forum/viewtopic.php?f=102&t=9970, it happened also to me, that i bought original versions.
I found in the DECK that I use, whatever it could be, some NON BASIC LAND contained in the AI custom DECK. Somebody knows already this bug?
Obviously it did not happens if you choose for the AI a Deck without NON BASIC LANDS.
