Product sign not updating

It seems that the sign on assembly isn't updated if you change the recipe, i think it's done once it starts producing.

Was like this in U2, too. I agree, would be nicer if it updated immediately (for an assembly not producing).

the problem is if an assembler has multiple recipes, so it dynamically changes.

Yes, but if it is idle it could update when you change the recipe. If not setting to the new 1st recipe (as it is speculative), at least remove the obsolete one.

Well i now understand why they update the sign only when it starts producing, just to show what it is doing currently, cuz of the multiple recipes.
