Thanks, I feel like an idiot cause I went down there, but I didn't think to actually go next to the gate. follow up question though, the game told me Patricia needs to see me one more time, or something like that, but I don't know where to find Patricia. If it helps, I have images 1-17 unlocked only.
That's for the last optional chimera scene - if you've done all the others (3 for Meleuma, 2 for Patricia, 3 for the Greenhouse), she appears in multiple screens in the industrial area to trigger it.
However, as a note, versions prior to the current release (16/07/19) had an issue that sometimes occurred when triggering the event, if you're using an older version and want to see the scene it might be a good idea to update before you complete the conditions.
