Tilecracks.xnb is in the Terraria 18.104.22.168 I just installed on steam. Not sure what is up. Another thing people forget to do when installing is forgetting to unzip the Content folder from the TerraCustom zip. Another common issue is people installing tmodloader or terracustom into the vanilla terraria folder and accidentally modifying the vanilla files in that process. I can walk you through any issues in real time if you come to my discord, if you want.Thats the rub, actually. I tried following the instructions first, but that was the same, only worse. The vanilla folder has even fewer of the files TerraCustom wants. Tilecracks.xnb is not a file thats installed when I reinstalled Terraria. I had to hunt it down from a four year old version on an old computer in the attic.
