When I'm in the replay everything works fine until i click to either add a position or time keyframe and then the game crashes.
This is the error it comes up with:
The game crashed whilst mouseclicked event handler
Error: java.lang.NoSuchMethodError: net.minecraft.class_129.method_577(Ljava/lang/String;Lnet/minecraft/class_133;)V
Anyone know whats going on?
