Cursed Jar graphics

[Mistah Knight]

So I just watched a youtube video of the cursed jar mission and noticed that the jars seem to have some sort of purple aura/trail... but in my game, no such thing happens and so the jar carriers look pretty similar to some of the regular workers at first glance.

I wound up getting the regular game and expansion during the steam sale (and am starting to regret it). Anyone else have this issue or know of a fix?

I checked options but all I see are audio and language options. Nothing for graphics.

Here's the video I saw: https://www.youtube.com/watch?v=uhIfZgt44fQ You can hear the jar carrier's laugh around the 50 second mark.

Have failed this mission every time I've tried it. No purple aura for me either. No way to know which ones are cursed that I've found. Do you happen to have a ATI video card?

I recently tried it again and it worked. Maybe there's been a fix? I'd try again.
