Prime never destroys the first force field
From my own experience, I had more then 17 crashes during final mission with EVE (0.96) installed, and only two without it. Please don't think I try to tell something against EVE, it is good mod, but very eager for resources.
Open console, click Liberty Prime, enter
EVP
(evaluate package). It must help. Known issue from vanilla game.

Please don't use FWE and FOOK together, they are incompatible.
FWE have most recent version of CALIBR included, but if it is not enough for you- here a link
