The Virus

I just created an account to thank Leops for this (and I suppose Crimor for asking). I started experiencing dead-stopped orbits and phantom accelerations three days ago, and I've spent the past three days reinstalling mods, trying (in vain) to decipher logs, launching test flight after test flight with different parts on board, finally narrowing it down to the presence of Universal Storage parts. I checked and double checked that I had the latest version, and minutes ago, finally found your comment. It works. By Jool, it works.
