Potential correlation, possibly more automation/chests causing more breaking? The kegs and jars connected fine for the longest time but I kept adding more and more auto chests and machines to other areas, THEN kegs and jars were having trouble automating.
Also potentially has to do with different items in different orders in the auto chest? Since it loads in order of placement in the chest. Using the kegs as an example, Ill put fruit in the auto chest to process, it loads to the kegs. When I return later the processed juices are in the first few slots before the remaining unprocessed fruit. Maybe the chests are getting stuck trying to process the already processed items so they dont move down the line to look at the unprocessed ones?
It would make sense why I see it happen to the kegs and jars (processes multiple items in one day) but barrels and hives seem fine (multiple days to process 1 item.) I move all the processed items at the end of the day, so if that is it and it fixes after I move things/next day it makes sense that fast processing machines noticeably break and the multi day processing machines seem fine.
