i am not able to get the ui to open in game.  it just says unknown command.  yes i have perms.  i was able to kinda edit in config to make bigger stacks but i need ui to make it right.

I face same problem.
I see in the .cs file the line 286

[Description("Modify item stack sizes using chat commands or config edits, UI Editor is now a paid feature")]

So I guess that would make sense why it does not open.

when did it go paid?  i wish we would have been notified it was going paid.

Sneaked in quietly it seems

thank u for letting me know.

due to umod's terms, i cannot advertise or notify.
i had it noted on the docs but i got in trouble for it.

That is crap on behalf of uMod then 😡
