Hi, afetr having had the same problem today today and coming acroos this post i did some more looking and came up with a solution that worked for me.

step3: under heading [mysqld] look for #set the sql mode to strict
step4: find sql-mode="no-engine-substition,strict-trans-tables"
step5:replace with sql-mode=""
step6:save file then RESTART PC
step8:rezzed animals out and set the names etc...
and its now working fine for me
