M1A2 Trophy research requirements.

Hello,

I’m a little confused on researching the Trophy. When I last played, I researched SEPv2 and did not research SEP(I rarely do foldered vehicles). Now, SEPv2 is foldered under SEP, which is a requirement to obtain the M1A2 trophy. The game is currently letting me research the trophy without the SEP. Will it let me buy it when I finish? I have a hard time believing no one at gaijin actually considered this situation. If a vehicle I was already past is a requirement now, I might not even bother continuing.
