Hello,
Thank you for the plugin.

I noticed when I close the shop interface (invoked from the command or NPC), my keyboard inputs are ignored, with the exception of "ESC". I can howover move the camera freely. To regain the full control, I must press ESC to display the in-game menu and close it to fix the issue.

I don't know if I am alone with this bug (probably...).

after that, few shops configured the same way at the exception of one named "Construction", with "EnabledCategory": true,
Also another shop I used with a NPC. (shops are work in progress :) )​

I tested with the default config of the shop, the problem remaine.
May be a problem with another mod? It is strange because I can move my character while the shop is open (keyboard input ok) but when I close it is happening. 🤔

Merged post

The problem seems to be linked with the close method used in cuibutton class.
I made a small change in the source code to figure out.
I created a method to close the interface with a command

        [ConsoleCommand("guishop.close")]
        private void CloseAllUi(ConsoleSystem.Arg arg)
        {
            var player = arg.Player();
            if (player == null) return;
            CuiHelper.DestroyUi(player, GUIShopContentName);
            CuiHelper.DestroyUi(player, "ButtonForward");
            CuiHelper.DestroyUi(player, "ButtonBack");
            CuiHelper.DestroyUi(player, GUIShopDescOverlay);
            CuiHelper.DestroyUi(player, GUIShopOverlayName);
        }​

            container.Add(new CuiButton //close button Label
                {
                    Button =
                    {
                        Command = $"guishop.close",//Hiro
                        //Close = GUIShopOverlayName,//Hiro
                        Color = "0.82 0.78 0.74 0.50" //Hiro
                    },
                    RectTransform =
                    {
                        AnchorMin = "0.45 0.14", 
                        AnchorMax = "0.55 0.19"
                    },
                    Text =
                    {
                        Text = GetText(_config.CloseButtonlabel, "label", player),
                        FontSize = 20,
                        Color = GetUITextColor(player, _config.TextColor),
                        Align = TextAnchor.MiddleCenter
                    }
                },
                GUIShopOverlayName);
​

With this modification, it close the interface and my keyboard input work properly.

I've never had an issue closing the shop.

I am unable to reproduce your issue.

Had the bug happening again few hours later... so my solution wasn't one.
Maybe a client side issue then. this doesn't make sense otherwise. I will do test with other players.

Anyway, I believe this is not related to the plugin itself so you can set as not an issue.
Sorry for the waste of time. :')
