I've had a few sim freezes while setting multiple GBU-24's and finally figured out that it only happens when using a custom waypoint.
Loadout doesn't seem to matter and I've been able to reproduce it on both Persian Gulf and Caucasus
Persian Gulf, heading to attack 2 ships in the East. AG master mode, GBU-24's armed, fuzes and codes set. After setting QTY to 2 on the UFC the sim freezes. I noticed it looks like it is automatically trying to program a massive INT which I did not set. This only happens when heading towards a custom made waypoint made through the UFC, if using pre-planned waypoints or no waypoint at all, it does not happen.
