Running latest open beta. Tried this in multiplayer Caucasus and offline NTTR.
When performing a toss bombing with a BDU-45, TGT designated, mode AUTO, MFUZ NOSE, EFUZ INST, DRAG FF, the plane does not compute the release time correctly, leading to impossible toss bombing with this type of weapon.
Tried with Mk-82 Snakeye and Mk-82Y, both with DRAG set to FF and the behaviour was equal to a normal Mk-82.
