I have the exact message, its saying
"Error while running event UsefulCombinators::on_tick(ID 0)
UsefulCombinators/control.lua:607:bad argument #1 to 'get_signal' (table expected, got string)"
This happens every time I successfully attach a circuit wire to the random combinator and something else. If I click on Random Combinator with a wire, it won't crash until I click on something else with the wire, connecting the two. If I click on something else first, it crashes as soon as I click on the random combinator. Please fix it, I only found the mod because I needed a way to generate a random number. I love the rest of your mod, but I really need a random number generator.
