This is also happening to me, although it started way before Eco Lifestyle. Last Expansion pack I had before Eco came out was before Get Famous I think it was Seasons. I don't think it's an Eco bug, I think it's just a Sims 4 bug in general and always happened after something was repaired.
Happened to me once but I never experienced it again after doing some stuff. What I did is I removed some unnecessary mods and deleted the "localthumbcache.package". I will report it if I experience this issue again.
I have the same very annoying problem, it happened twice, basically, my sim was interrupted while fabricating something (she needed to go to the bathroom urgently) and the interruption caused the never-ending glitch sound.
I was able to fix it by reloading the game the first time, but not the second.
This is happening to me as well. Deleting the object, replacing the object, bulldozing the whole lot, replacing the lot, all do not stop the sound of the fabricator from where it once stood. I can only shut off sound effects in settings to not hear it anymore, or just never play that lot again.
I, like another user, have found that deleting my cache files does seem to at least temporarily fix this problem.
Fixed an issue in which the Fabrication sound effect continued playing even after Fabricator had completed ist task. Had the Fabricator become sentient… self aware?
Fixed in Patch 1.64.84/ 1.28
