Bots with a capacity greater than one will now place more than one tile per trip. If they are replacing more than one type of tile on that one trip, they will only be able to carry back the first tile type they pick up.

To replicate, place a 2x2 checker-board pattern of stone and concrete, then shift-click it with a 2x2 brush of hazard concrete. With bot capacity +3, a single bot will place all four hazard crete tiles, but will only carry back either stone or concrete, leaving the other item on the ground.

Perhaps auto-mark the dropped tiles for deconstruction?

Thanks for the report. This is something I knew about but forgot to have the robot mark them for deconstruction. So, now they'll do that for the next version of 0.17.
