All right, I have pushed a new update. This issue should be fixed. I have also released it to 2.1.
Version: 0.3.4
Date: 2026-09-27
Features:
- Chests can be primed. Point the tool at a wooden, iron or steel chest, ghost or built, and its window opens with two modes: Recipe, which works exactly like a machine's, and Items, which lists individual items and counts instead. A chest feeding a machine through an inserter opens straight onto that machine's recipe.
- Items mode: add a row for each item you want, and set it with Half, Max, a slots slider, or an exact count, up to what the chest holds beside the other rows.
Changes:
- Dragging the primer tool now also lights up chests, and a drag over a row of chests primes them all, the same way a row of machines already worked. A drag centred on a chest skips other chests, not nearby machines, and the other way round.
- Clicking a logistic chest, or hovering one with ALT + P, now explains that logistic chests can't be primed, instead of doing nothing.
Bugfixes:
- A group's area Blueprint now also carries other already-primed machines and chests standing in the dragged area, not only the group itself; their requests were silently dropped before.
- Fixed a fixed-recipe read that returns a different type on Factorio 2.1, ahead of a future 2.1 release.
