as my followup comment in my last post has been ignored, here a new bug report..
with the update to 1.1.6, the long-inserters-1 tech has been disabled, which makes it impossible to make long-handed inserters (be it with Shift+L, or the actual red inserter).

I have disabled the inserter overhaul, but I have the same issue.

I can't build long handed inserters, and the long handed research is gone. But if I enable inserter overhaul, then the long handed research is back.

Fixed for v1.2.0 Sorry for the delay!
