The exact same issue troubles the bazaar item Arcane bookcase. The problem is that the open/close animation plays when player accesses the container, but not when they close the container inventory window. Leading to effective “desynch” of the open/close state of the item.

I hope this following sequence explains it a bit better:

  • container (special container, arcane bookcase) is visually closed.
  • Player accesses it with interact (E) button. The animation plays and the container visually opens and remains open.
  • Player closes the container inventory window with esc. The container STAYS visually open.

  • container is visually open.
  • Player accesses it with interact (E) button. The animation plays and the container visually closes (because it was open to begin with)
  • Player closes the container inventory window with esc. The container stays visually closed.
