Upon updating my mod from 1.6 to 1.7, I found and fixed most of the errors within the code. However, there are four bugs which I do not have a solution for:
TileEntityBoiler:
NBT data does not seem to save properly myself, and another coder looked at it and could not find an issue.
All custom item icons:
None of the items that I have made render their icons properly.
EDIT: this now just applies to items, no longer blocks.
All custom items:
Whenever I leave the world with custom items in the player's inventory and log out, the client hiccups when logging back in and the player inventory becomes corrupt. I have no idea why.
here is the forge log
