We had this too, with a chopper. That's bad since the sorter is one of the only ways to suck out specific items from Progressive Automation, and they're the only way to automate farms/wood. :/Just got a world ending crash on my server, apparently Mekanism's Logistical Sorter will pull upgrades out of a working Progressive Automation machine, which causes a ticking entity error. This happened with the planter specifically. HAd this happen when I was trying to keep Router Reborn's storage units from over-writing the items already inside of them.
