[quote="arihakala"]I think the problem may be that i did not choose anything from "city selector" (because it was already displaying "all"). But maybe selecting is actually required for this to function correctly? I tried this again and selecting "all", and it worked fine.[/quote]

I did a test and I didn't have to select "All" on the interface and it worked well with batch switching supplier.

Could you try again? And see if it works the same for you?

And did you mean the "All" selector on the firm report interface (see below image), or the "All cities" selector on the Select Supplier interface?

I tested the Batch Switching Supplier function in the latest v2.3.04 version and it worked well.

Did you follow the instructions on this page?

If the problem persists, could you provide me with your save game via Dropbox and let me know the steps for triggering the bug with the save game?

Batch change has never worked for me. It always only changes one store.

I have set up stores in each city and produce goods in one location.

When demand goes up, i add another factory and set up warehouse to handle distribution.

I would like to use "batch change" to change my stores use warehouse instead of factory. But it seems to have no effect. Batch change says something like "x stores updated", but nothing seems to be changed.
