I think what is happening is that they are trying to make it really realistic or just ended up like that without actually realizing it IRL slag sometimes can trap some iron due to how this type of smelting works, i think that its the same thing happening here You smack some slag off and it might take off 1 voxel of iron with it, get unlucky and you end up with voxels missing due to how the game works If anything we are lucky that slag doesnt generate holes in our blooms IRL blooms were just random sized chunks with sometimes slag trapped inside and took long time to work them out of the metal While its annoying at least helve hammer can fix them and you should have mechanical power at that point of progression In my opinion the only thing they should do about this is to add some information in the handbook, that if you cant finish the bloom you need to use helve hammer Ill be honest it still irks me that 1 bar is 1 knife blade instead of at least 2 but this is not the topic on hand

Not so rare in my case, time to make the helve hammer i guess as i do have most of the things for it Ended up with 2 duds missing 1 voxel in 12 bars
