need help! Sims disappear during sex

[black_ravens]

have run into an annoying problem where sims disappear after climax animation and I need to use ww.stop_all_sex to get them back.

error message comes up that i have an outdated mode. this past weekend has been spent going though them to weed out the older modes.

but after going through them and pairing them down the error has come back.

attached is the last exception.

so if anyone can find the fault that would be great - thanks

I've included the BE-exception report for further information
