Forum:Two Field Spells that change a Monster's type

Just wondering what the ruling would be now that both players can have a field spell at the same time, like I have Zombie World active and another yet be be released field spell that also changes type is activated, what happens? Do the monsters on the field get dual-typing? Or does the last field spell to be activated take priority?

Also what happens when someone uses DNA Surgery after the opponent played Zombie World?

Thank you for your time.
