More Awesome Than You!

Today I decided to finally let Cassandra Goth and Don Lothario get married, since I'd deleted all my saved games and everything else before I installed Seasons on a fresh new game. So I wanted to throw a wedding party, and I invited regular folk and a Plantsim I made yesterday. When everyone started to enter the lot, I kept getting an error. I can't remember the exact words, but it was something to the effect of "object must be human." I'm only using FFS and TwoJeffs hacks announced as compatible with Seasons. The error wouldn't go away no matter how many times I clicked reset or ignore, and I've conditioned myself not to click delete. Finally I just had to ctrl-alt-delete and close TS2.

Any ideas/anyone else had this issue? If we're not supposed to be able to, will there be a fix out so I *can* invite Plantsims to parties?  :-\

Edit: Including part of the error log, displaying what I saw on the screen. If anyone wants the rest of the log, I'll attach it.
