I think it is similar to problem #51 , as my problem is that i have a drawer system with void upgrades, but i tried to fix this problem by adding more drawers and i had gotten to the point to where it wouldn't add them to the drawer. The drawers have empty slots with nothing being inserted into them, but items to be inserted into them. It refuses to add existing items into the drawer controller as well. My guess is that it isn't registering that their are more spaces in the drawer system.

Not that this is a proper fix for the issue, but, a workaround I've found is to use RFTool's Storage Scanner as an intermediary.
The Translocator can correctly insert to the Storage Scanner, which can be configured as routable to the Drawer Controller or Drawer Slaves.
Also, in my own experience with this issue, the Translocator has no issues extracting from a Drawer Controller or Drawer Slave, so the fact that one cannot extract from the Storage Scanner shouldn't be an issue.

It really isn't a proper fix though.

just destroyed it and placed it again, and it filled two different spots, but still doesn't recognize some of the others
