ToME: the Tales of Maj'Eyal

I found that any fire or cold damage that kills the enemies will not be accumulated in Pyro/Cyromancer Achievements. I spent a lot of time in making fire/ice dmg (using Archmage class) and when I am about 12-13 level, I found that my pyromancer achievement is still 40k++/1000000, which doesn't went up. At last I found that if any amount of fire and cold damage I inflicted had killed the enemy, the amount won't add in the achievement. Only the damage doesn't killed them has been counted. I did the same experiment with a new character (Alchemist class), and it show the same result. I wonder if it is a bug. This problem has hindered me doing 1000000 fire and cold damage, which is necessary to unlock the Wildfire and Ice Talent Trees. I hope this problem can be fixed (or be clarified if it is not a bug) soon.

p.s Version I play is 1.1.5

Please, tell me, how do you check the progress of damage done? ^^

In main menu (default [esc]) there is a " Show Achievement " option~
Choose "Everything" and you can find it.
