Why do my rails now need an extra button to function?

[Reilly Reese]

Version 199.435

This rail logic successfully works in 435 without a button, however in the latest game release (472) I need to add another button between the NOT gate and the Rail in order to achieve the same effect.

What's the reasoning for this?

Because nots are weird.

I don't know what that circuit is supposed to do, but I assume the issue you describe is due to a change in NOT gates. Namely that NOT gates can no longer change a rail block? Maybe some more context would be useful. Like what does this circuit do? What do the connections look like?
