If I place splitters/mergers on an existing conveyor belt, its automaticly managing the connection between conveyors and splitters/mergers. So far so good, theoretically.
But, there's a huge mess in this feature:
If you remove such a placed splitter/merger, its trying to fix the conveyors again, by rebuilding the conveyor belts (any ressources on the conveyor are lost!!) but looks like to me, its putting more than one conveyor belt into others, they act as a single one if you remove them.
Items delievered now, are bouncing forward and backward. Im not sure if it's just a visual bug, since I noticed different results.
Solution: Rebuild conveyor belts everytime you remove a splitter/merger placed on an existing conveyor belt.
If you place more than one splitter/merger in a row, there's no solution other than placing splitters first (need to stack from ground....) and make some room between them, so you can manually connect everything...which kinda makes this great feature completely useless..
PS: conveyor belts sometimes even go through the attached splitter.
For me, this bug is one of the worst, since the workarround takes so much more time to build. Thanks for looking into this.
