(See the best response by Kaiochao.)
Code:
for (var/mob/m in world)
    if (m.client)
        spawn()
            m.client.images += oMoveHighlight
            sleep(2)
            if (m.client)
                m.client.images -= oMoveHighlight // <-- Hit exception here


Problem description:
Hitting null exceptions in animation code when a player exits the game during an animation.

This code is spawned by one client to animate all other clients.

Is there a better design I could try?

for(var/client/m) could be used in place of checking for mobs then checking if they have a client.

Are you deleting the mob when a player exits the game? If so, you should be checking if 'm' exists before trying to check null.client. It should tell you this in the run-time error you're getting.

Alright, I just added checks for m and that seems to have fixed it. I wrongly assumed m was safe and mis-read the run-time spew.

Thanks!
