This is with Crossfire 1.7 installed.
I have been playing for a couple of weeks now, finally have an Eagle and getting ready to explore the additional systems. Went to Junyo and bought a Mark IV shield upgrade. Before this, game is working fine. So I'm traveling through Galileo heading back to Oasis, now that I've got some muscle :), trade lane is disrupted and as soon as I shoot a ship, I get CTD. So, instead of heading to Oasis, thinking it's just a bad save or something I resave and take a mission on Junyo and same thing. As soon as I shoot a ship, CTD. Is there a known bug with the Mark IV shield upgrade?
Only other thing I can think of that I did before combat is also bought a scanner upgrade.
