Hi, I noticed a possible issue with the Superior Long Inserter in Factorio 2.0.77.

The inserter tooltip shows a large hand stack size (5 + 39 in my current game), but when placing items onto a belt it deposits them one at a time instead of creating belt stacks.

For comparison in the same save:

Bulk Inserter: max belt stack = 1
Stack Inserter: max belt stack = 250
Long Bulk Inserter: max belt stack = 1
Long Stack Inserter: max belt stack = 250
My researched belt stack size is currently 32

So it looks like the Superior Long Inserter may have max_belt_stack_size = 1, despite otherwise behaving like an endgame/stack-capable inserter.

I locally tested setting its max_belt_stack_size to match the normal Stack Inserter, and that fixed the issue; it then correctly uses my researched belt stack size of 32.

I’m also running kry-inserters and long_stack_inserter, so I can’t completely rule out a mod interaction, but I thought I’d report it in case the Superior Long Inserter prototype itself simply doesn’t set max_belt_stack_size.
