Lately my sims have been getting stuck in hammocks while on vacation.  They begin to read and then when another action appears, (for instance- leaving or checking out) the book disappears and they are stuck there unless I exit the lot and reload it.  I was wondering if this was a known issue or if anyone else has this problem.  I just would like my sims not to die if I don't notice they are in the hammock.  Well most of them that is.   

   Thanks.
