this is all i've found so far: Using missing texture, unable to load tutorialmod:textures/block/linaflower.png : java.io.FileNotFoundException: tutorialmod:textures/block/linaflower.png

Found the problem, Turns out even though I changed The texture name to lower case, My computer for some reason would not update the name. So I just copied and pasted it, and for some reason, That updated The name to all lower case, why? I don't even know. Sorry for wasting your time, on this stupid little mistake.
