go view the picture for my crippling bug. The rotary macerator is attached to nothing. I put a stack of cobble in it FIRST, and then a fully charged battery in the battery slot. It tries to process 1 cobble, but stops receiving power from the battery one the processing starts. Please help, this bug will completely kill my logistic factory
edit: a transformer upgrade fixes the problem.... but this is for a regular tier 1 battery...
Edit 2: apparently, the transformer has some weird bug where you need +1 transformer upgrades for the machine to accept power from batteries (ie 2 for mv energy crystal instead of 1, 3 for a lapitron crystal or hv energy instead of 2)
