[fixed]Crawlspace makes permanent become swamps

Describe the Bug:
1- Crawlspace controller's opponent can't attack with 2 creatures.
2- Every permanent and effect cards (Rules Engine at least) of opponent becomes a land he owns with swampwalk! and triggers combat effects all time.
Which card did behave improperly?
Crawlspace
Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Manalink dev 2067e779 version - duel
What exactly should be the correct behavior/interaction?
1- No more than two creatures can attack you each combat.
2- Doesn't trigger combat effects all the time and doesn't go beserk.
Are any other cards possibly affected by this bug?
