Bug (?): Acquisition during research

[Glitch]

I am not exactly sure if this happened or not because I am new to the game but it appeared to occur. I am trying to replicate it (but again I am new to the game).

I was in an early war with and so I started researching Physics I. I had two turns of research left when I captured the enemy homeworld by forcing them to surrender. As part of their surrender they gave me Physics I. Now, in the research queue I was researching Physics II, but the scary thing was I still only had two turns of research left.

I'll post back later today if I can replicate it, but has anybody else experienced this?
