I cannot seem to get anything into the permit chest, using short or long inserters.

I didn't try the solidifier, but since you cannot limit it, it wouldn't really help anyway.

Shoot that’s definitely a bug, and a tricky one as factorio engine does not like overlapping items, but at the same time does not allow us to attach buildings nor modify the train station enough…

I will find a fix !

Could place the chest specfically offset and matching rotation, outside the station.

If it can't be fixed quickly, a game setting to toggle that might be sensible.

Adressed in 0.2.7 !
