In Mekanism 9.0.1, if you attach a Logistical Sorter to a Personal Chest, and also have a Logistical Transporter attached to the sorter, the game will crash as soon as you apply a filter. It does not seem to happen if the sorter is attached to the bottom of the chest however. Attaching an example crash log.

I believe this was fixed on the dev branch. you either have to wait for the release branch or build the dev branch yourself.

Yeah, fixed :)
