After a slug is released, it will not move on to a merging conveyor in one situation (view Problem_Yes), it works fine in another situation view (Problem_No). I have tried and tested quite a bit and I get the impression that the conveyor system is a bit unstable?
I am using the power and free conveyor type. Using it, creates a number of issues, but I have been able to handle most of them. I.e. having an short accumulating conveyor when merging between P&F conveyors.
There is also a problem when an dog is to catch an item. I use the default, catch leading edge, but sometimes it catch the trailing edge - which creates problems.
