You might also look at this question, which shows that you can have the same problem in a fixed-effects model even without an interaction, and this answer, which (1) explains how order dependence in the default R "Type I" anova() or aov() is to be expected in unbalanced designs and (2) provides a link to a discussion of different ANOVA types in the help page to the Anova() function (capital "A") in the R car package.
