When I have forestry installed it crashes on start. It goes straight to saving world instead of the main menu for some reason then crashes. Error: java.lang.NullPointerException: Rendering overlay, that's the error message I'm getting.

it also crashes with iron furnaces. Error: java.lang.ArrayIndexOutOfBoundsException: 0, is the error message I get. Neither of them error with Electrodynamics-1.16.5-0.4.0-1.jar though.

1.16 is no longer supported :/
