Not sure if this is on Quark or on Iron Chests, but if you have a shulker box upgraded (extra inventory), and you use the "right click to add items" to shulker box feature, everything in the chest gets deleted after the last visible item in Quark's shulker box preview.

Also, using the "right click to add items" only works sporadically, and never when the shulker box is in the hotbar.

Thanks for a brilliant mod. <3

This is jarring...


Everything that does not show up in what shows in the hovered inventory, gets deleted.

This might also be an issue with iron chest's mod as well.
