I had no bugs that I noticed. Everything runs brilliantly on my very old computer, and I added horses, sheep and goats to a large number of households. I'd say this is one of the packs with very few bugs, so I would not wait just because of bugs... I hired a farm hand only once, figured it was not suitable for that lot as I was playing a noble household where it looked wrong when the filthy hired man walked around the big house to use the sinks etc. That was not a bug though, I assume farm hands are meant to walk inside clean/fix things, and I will probably use them on more ranch-like lots, and not for a manor.
