Got the question mark on flame in ML and multiple sprite errors. Just passing along.

That is a problem caused by some character sets not having the full suit of sprites to cast spells or bow/wave.
Flames are one set missing these sprites. Spiders also used to be missing these sprites but we added them back years later.

There are two possible solutions:
1) Fill in the missing flame sprites with new ones
2) Stops the flames from casting spells in combat. It may be part of the randomisation of skills that has allowed the flames to gain spells to cast (not certain).
