Not receiving full science from transmitted EVAs and crew reports

[-Velocity-]

I did a search for this and couldn't find it.

Can anyone tell me why, since 0.24, I only receive a fraction of the science I'm supposed to get when I transmit an EVA or crew report? I have PLENTY of electricity (literally, thousands of units, and transmitting only uses a tiny fraction of that), and I am using the highest gain antenna. So when I do an EVA or crew report, it will say I can recover 100% of the data by transmitting. Say I'll get 60 science. However, when I transmit, most of the time I get like 14. Or 20. Or some random fraction of the amount I was supposed to get.

So afterwards, I can do the same crew report or EVA again, and it will say, this time, I'll get like 6.4 science, with 100% transmit value. So, I'll transmit, and instead get like 1.3 science.

It doesn't always happen either. Back when I was doing this career's round of Mun exploration, I found that if I used the monopole antenna (the straight one), I'd have this problem, but if I used the cylindrical antenna, I'd get all of the science I was supposed to get.

WTH is going on? The only mod I use is Mechjeb.

Are you running x32? This is a known problem in x64.
