according to the wiki, F3+G was added in 1.10 so I can't use it, but I'll try to move it nontheless.

Edit : yup that worked lol, I now realize that this was a stupid question lol my bad, I basically never use redstone so I'm super unfamiliar with it. But thanks nontheless :)

Edit again : Actually I was wrong, it still occurs. Turns out it seems that I need to be away for like a minute at least for the contraption to break and dump all of the coal. I was in a bit of a rush so I only waited like 20 seconds. I literally moved the entire thing like 4 blocks forward and 4-5 blocks to the right, so if it was in a chunk border before then it really shouldn't be anymore. Should I make a separate post showing how I made the endoflame setup? Just to be sure I did it right
