So im currently running 0.3.2b and im not sure exactly what happened but this morning the smart chute scroll function was working and this afternoon, while previously placed smart chutes have the scroll function, if i place down a fresh smart chute i cant use the scroll function (so that u can specify the stack size the chute uses) and also the overlay looks different with no asterisk and no scroll text (see photos). i also tested this on a server just in case i changed something in singleplayer i wasn't aware i changed (i run the server and know for certain none of the files have been changed in the last 6 days) and had the exact same issue (including the old smart chutes working fine) i also tested the brass funnel and brass tunnel. the brass funnel is not affected by this but the brass tunnel is. i also know its not just a render glitch, cause when i scroll on old smart chutes it both updates the number and also my selected item in my hotbar doesn't change, but on freshly placed smart chutes my selected item immediately changes, in the same way it would change in normal functioning of minecraft. current workaround is to use a brass funnel instead of a smart chute.

The smart chute is designed to only make the count configurable whenever it is extracting from an inventory directly. Could this be what you are running into?
Brass Tunnels also have no amounts to configure, either. Their filter can only control the type of item, not its stack size.

ah yes you are correct. sorry for the false report
