Resource names should not have spaces in them, this causes certain things to break (in particular, the Custom Image item from FTB Quests, causing the error [10:38:47] [Render thread/INFO] [STDERR/]: [com.feed_the_beast.ftbquests.gui.SelectImageScreen:<init>:42]: net.minecraft.util.ResourceLocationException: Non [a-z0-9/._-] character in path of location: betterendforge:textures/block/thermal fungus.png)

And also any other resources that have space in them, idk if there are any. It could just be stopping at the first one.

Mmm what?? I don't remember this being an item/block in the mod..probably just an unused texture that i copy-pasted in the folder along with the other textures...i will investigate, thank you for reporting!

Fixed in dev code
