Had this happening twice now on my headless server with mods, when I'm removing a multiple buildings without any radar buildings in the game, the game crashes and giving the following message:

The mod Quantum Fabrication (2.3.4) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event quantum-fabricator::on_tick (ID 0)

The following Mod options are enabled:

Startup
- Enable space transfer?: Yes
- Enable auto repair?: Yes

Map
- Enable decrafting?: Yes

Per player:
- Send directly mined buildings to the Storage: No

Looking at the error, the crash is caused by construction, not deconstruction. The mod tried to craft a building, succeeded, but failed to add the crafting result to the storage.

Gonna need more info here. Can you share a save? Or at least a modlist, but a save would be better.

i think i have solved the problem, it is with another mod 'Loaders Modernized' https://mods.factorio.com/mod/loaders-modernized

At the default setting it blocks the recipe for long-handed inserters. Since i enabled the recipe again, it has not come foward luckily!

Alright, let me know if the issue reappears.
