The mod Market caused a non-recoverable error.
Please report this error to the mod author.
Error while running event Market 2::on_gui_click (ID 1)
market2/entity_guis.lua:147: in function 'entity_gui_click'
market2/guis.lua:113: in function<market2/guis.lua:40>
To replicate:
0: Be on a server with the Market2 mod installed. Make sure you are not server owner. (also used Market Autobuy but that shouldn't be too relevant)
1: Place a Market Chest.
2: Have someone else edit chest settings.
3: Open the chest yourself.
3.5: Have the server owner delete the chest, or edit the settings.
4: Exit the chest menu.
4.5: You will have the Menu of Server Death. It persists between saves.
5: Click anything on this menu and the server will be dead until it restarts. All progress from last save is lost.
(Not sure if this is exact process but still, please fix by adding an exit button to the menu that does not change the values of the chest in any way.)
