[Items disappear after quest finishes]

Where did you place the box? If you placed it close to where you are doing the quest, that is your problem. When you start a quest it resets the area around the quest location. Some players will even use this to their advantage by looting the quest poi first and then starting the quest so everything respawns.

I myself lost my gear first time I did a quest by placing a chest next to the poi before starting the quest. Now I make sure I am well away from it if I want to place a chest down first.

I also had trouble with my server because of this line.

I had to update it to Microsoft Visual C Redistributables 2022.

It worked fine for me after that.
