Found a partial incompatibility with the Stardust UI mod. The game does not crash, but the sort button does not appear.

thanks, i will have a look
if you can provide more info, or maybe a log that will be helpful in fixing the issue, thanks.

@COVID-19 Well... Error logs - hardly. I did not notice any critical errors. "Stardust UI" simply replaces the bottom of the inventory window with its own functionality, causing the "Food Stack" buttons to not appear.
I can share the log with the new character and new universe, but after a quick test where I ran around and opened a few containers, I did not notice any errors other than the one described above. If only I knew how to share logs here...

I use stardust core lite, but I'll see if i can isolate the issue.
Log in that case doesnt sound incredibly useful but there is pastebin if you wanted to drop it there anyways and share a link.

Just tested to see the issue, and foodstack's stacking functionality doesn't appear to be present at all, even within fridges where it is normally enabled. At least for me.

My best guess as to the cause of the issue would be that Stardust's inventory system calls a custom script for UI interfaces. One which foodstack doesn't interact with.

I might look into it some more, but since I don't use nor understand Stardust UI I'll be honest with you, it's not on the top of my list of priorities.

@COVID-19 No problem, I understand. In any case, thanks for responding.
