[Mobhack]

Is the missile to-hit animation messed up with at the same time as this is happening?. If so I suggest the same thing as with that - save and exit the game and restart, sometimes with a reboot of the computer if it persists.

The missile hit animation hiccup seems to be related to the intel integrated graphics, but I cannot for sure say it is so. It can happen in mid game, and if you proceed it can go away and then return - or it can be "stuck" - and an exit and restart usually fixes that. Then it can go away for weeks and suddenly return.

Since I never play with sound on I cannot for sure tie the problem to that, but I do have my suspicions!
