So basicly after I use the 'change order' scrolling rod disappers so as I am on a laptop I cant scroll down but if I reload the save file (created newly) it appers back.
I'm still looking into other solutions, but the simplest and most effective so far has been to enable horizontal scrolling in the slave list.
In file Mansion.tscn, line 1125 should be "[node name="scroll_list" type="ScrollContainer" parent="charlistcontrol/CharList"]".
Find and delete line 1136: "scroll_horizontal_enabled = false".
