I'm posting this here (instead of using the bug reporter) since i'm not certain if this is reproduceable in reasonable time without explicit access and modifications to the internal script, and would thus ask if somebody else observed this bug.
The base premise of this bug is that my player owned factory (Power Units) got selected as target for spawning a black market via a "the package" quest, with the specifc sector being controlled by a NPC factions. After some time i've realised that my station didn't sell anything (which wasn't that surpising as with 500% event rate most sectors are constantly hazard zones) so i checked in and realised that my factory stopped producing goods, despite having all the input items and space for the product (both in total cargo space as well as product limit).
From what i can tell the station still buys input goods (in enabled), i'm unsure if it still sells products as most trade ships are (presuably) part of the black market script as they carry stolen cargo.
In terms of additional information, i think between the spawning of the quest and starting the first phase (i.e. getting the package) there might have been a resetting to backup, but i'm not 100% certain on that.
