So you need to remove this block

-- Block being tesselated --
Details:
        Block type: ID #2395 (tile.tconstruct.casting // slimeknights.tconstruct.smeltery.block.BlockCasting)
        Block data value: 0 / 0x0 / 0b0000
        Block location: World: (258,73,227), Chunk: (at 2,4,3 in 16,14; contains blocks 256,0,224 to 271,255,239), Region: (0,0; contains chunks 0,0 to 31,31, blocks 0,0,0 to 511,255,511)

Easiest way (if it works) is to edit the forge.cfg file in config and change the line about removing erroring blocks to true. Next option is to use MCEdit to remove the block at 258,73,227 which looks to be casting table from TiC.
Ether way MAKE A BACKUP of your game before you do either option.
