Since the last update (Quark-r1.5-147) on April 29th 2019 the integration for sorting and store items on chests by Iron Chests is not working anymore, the button do not display and if i click on the store button of my personal inventory the items are not stored either.

No update of Iron Chest was made between the integration was working and stop working, so I am assuming it should be something changed in Quark

Also the same buttons don't work with Ender Storage, but in this cases they never worked

Tile entities now need to be manually whitelisted to work with dropoff.
