Attempting to craft torches using creosote oil, wool, and sticks causes an "out of bounds" crash. After initially encountering the error on a multiplayer server with a few other mods, I tried again in a singleplayer creative world with the same mods, and once more in another singleplayer world with all just Immersive Engineering and JEI. In all cases, the game consistently crashed every time I attempted to remove the torches from the output slot of the crafting table. I also tried it on both the engineer's crafting table and the vanilla table -- same crash either way.

The crash does seem specific to this recipe, not creosote buckets in general, as treated wood crafting works just fine.

IE version: 1.16.4-4.1.2-129
Forge version: 1.16.4-35.1.28
(Probably worth noting, I have used this recipe with no issues on a different world running IE version 1.16.4-4.1.2-128.)
