Issue
"LLC (or smth) has detected a problem rendering a block" and then, after a few seconds, game crashes. Tried using the same world with a new copy of modpack - didn't help. Quite a long time ago had problems with rendering sand in the TiC smeltery - I dumped a bunch in there, and it didn't all smelt due to insufficient fluid capacity of my smeltery, and after that sand started glithcing inside the smeltery (both the smeltery interface and, you know, The Smeltery), but it didn't affect anthing, so I was, like "nah, whatever".

!!P.S.!! I've seen an issue of "coduaha", and I WAS crafting Mekanism tanks, and my Crafting Table from TiC does not render when the world loads, but it still crashes afterwards, presumeably because Mekanism tank is render in the crafting grid on the Crafting Table. Should I just delete the crafting table via WorldEdit?

I recommend that you try updating to 1.59a first, but if that doesn't work, yes delete the Crafting Station :)
Please let me know how it works out.

Updating fixed the issue - now Basic Fluid Tank from Mekanica is just a purply-black cube on a Crafting Station. Had to restore my settings manually tho - kinda sucks

You can just move the new config, mods and script folders into your old instance, after deleting the old versions of those folders.
