Was researching a tech at x100 cost and my bulk inserters would put in 200 of one type of science to the lab then deadlock waiting for their hand to empty. It looks like regular recipes have allow_inserter_overload to prevent this; is there something like that for tech recipes? Or do I just need one dedicated inserter for every science type?

This was supposed to be fixed in a bug report, I'll reopen it.

In the meantime, this isn't going to work with chained labs unless you limit stack size to 1 and ideally filter inserters to spread load between them.

I've updated my mod so you can get around this issue as well, since there's also been an issue with another mod not expecting changes the way I originally made them.

It looks like line 98 of data-final-fixes is causing an error when the new setting is enabled. After I deleted that line factorio loaded properly and everything is working right. No more deadlock
