What makes it worse is that there are no other 31-cell solutions.

...which I wasn't actually expecting to find, given I couldn't get lower than 36 at first:
x = 11, y = 11, rule = LifeHistory2A$C2.C$2.2C$3.A.C$3.C.2AC$4.C3.C$5.A2.A$AC.A.C3.CA$CA.CA5.A$7.A2C$7.C!

Thanks for the inspiration, dvgrn.
I'll hold off on submitting since people appear to still be working on the bump.
For reference, I also have a 47-cell solution to that one, although Gamedeziner's looks much more conducive to reduction in the top right:
x = 12, y = 15, rule = LifeHistory7.2A$6.A2.A$3.AC2.C.C$3.A.CA.C$6.C.A.A$4.CA3.C.A$4.C5.AC$5.C$3.A.C$.2AC.CAC$A7.C$.2C.AC.A.C$2.C.A3.A.A$2.A.A4.C$3.A!

EDIT: Yup, there it is:
x = 13, y = 13, rule = LifeHistory5.2A2.A$5.C2.C.C$6.CA.C$7.C.A.A$5.C4.C.A$5.CA4.AC$6.C$6.C.2A$3.AC.C.C$4.A.A2.C$.A2C2.C3.C$A2.C.A5.A$2A2.A5.CA!

Here's a much easier one. Don't use scripts, please! I already found the smallest solution (at least, to my knowledge).
x = 6, y = 3, rule = LifeHistory5.C$4C.C$5.C!
Life is hard. Deal with it.
My favorite oscillator of all time:
x = 7, y = 3, rule = B3-r4j/S2-i3o5bo$2o3b2o$b2ob2o!

I doubt there is any smaller solution than 16:
x = 7, y = 5, rule = LifeHistoryA2.A.CA$4C.C$5.C$2A3.2A$2A!

There actually is, though. I'm hoping someone finds a 15-cell solution, because I couldn't come up with one. Didn't use a search program, though, as requested.

I won't ever say what exactly I get when using WLS for this, unless it is requested. Since Hdjensofjfnen requested that no one should use scripts, I will not reveal the patterns I found even upon others' request.
With that caveat in mind, I can confirm that this is an optimal solution. There is one more optimal solution (excluding flipping along the x-axis).
