No items from Decorative Tresure chest (Cruel Laby)

Hi, i opened a Decorative Tresure chest in Cruel Laby with a Enduring Warcry (Howl of the Wolf skilled) and no items dropped from the chest . After leaving the screen and running pack the Chest is closed again but not usable/clickable. (disabled loot filter in second screen shot)

Tried another one no drop after opening with Warcry.

Bug ist repeatble tried in another run still no drop.

In the next run i removed the Warcry from leftclick to prevent to accidentally open the chest normaly opened it and it droppend "normaly" (Heart of the Garggoyle)
