After upgrading the mod from 0.13.2 to 1.0.0, construction robots want to fly to every miniloader and chute that they can reach and do something with them. When the robots touch a miniloader or chute, they generally spill some items to the ground, which the bots then pick up. Some items are apparently already spilled without the robots touching them as soon as I load the map with the mod upgraded, and some of these are even spilled onto the wrong belt, perhaps because there was no space on the ground nearby.
An example save from before the mod upgrade is available at "https://drive.google.com/file/d/1e1edwoOc4K3aPiNC-LFgP-EU0dza-Tds/view?usp=sharing" . If I open the save with Miniloader 1.0.0, the worst spot seems to be around [gps=-78.5,460.5], where some green chips are spilled onto the yellow science belt, and the rocket fuel belt gets green chips, rails, and solid fuel on it, thus clogging the rocket fuel belt. If I open the save with Miniloader 0.13.2, there are no spilled items and everything seems to be working fine.
