I´m stuck with altium 23.0.6 (stopped paying for it). I think from 22 to 23 the gerber generation panel was all changed. Nothing new was added that I could notice but a very nasty bug:

The option to mirror the gerber is missing from the bar (seems it´s hidden at right but I can´t move it). Can someone with a newer Altium version generate two Outjob files, one with a layer mirrowed, so I can open it with a text editor and track how to mirror a layer by hand?
