Reseting did nothing, sadly. It's an asparagus staged rocket so I've been changing staging in VAB extensively as is. I'll try to comply with these guidelines as best I can... KSP Version: Steam. 32-bit as far as I know, although I'm on a 64-bit machine I was under the impression Steam automatically launched the 32-bit version. What Happens: Instead of firing all four Kerbodyne-sized decouplers which are grouped together in a single stage at once, they fire one at a time. I don't know how to replicate or work around. I can't seem to attach files, but here are some screenshots:

I'm having a weird staging problem on a rocket where four Kerbodyne-size stack decouplers are meant to fire at the same time. Instead, they're firing one at a time - I have to hit the space bar four times to get them all off. The decouplers were attached via four-fold symmetry, they weren't put on one-by-one, and I've definitely got them all grouped to fire at the same time. I'm not messing with the staging in-flight at all. The only possible cause I can think of is that I used control-z once when I was building the rocket. Completely clean install. I'll post a picture as soon as I can, provided I can get a good one to illustrate the problem.
