I've already submitted a bug report, but figured I might as well cover both bases and post here as well:
One of my KDF-allied Romulans (level 65) has over 50 of each of the three ingredients to craft the modulator. I click on "okay" to fabricate the modulator and nothing happens. I can click on the "okay" button 10 to 20 times and nothing happens. I beamed up to my ship; beamed back down again; still can't fabricate the modulator. I'll try again tomorrow. Maybe logging out of STO and logging back in again will get around the bug. Not sure, but can't hurt to try. (Btw, I've already successfully fabricator the modulator for my other KDF-allied Romulan, who is also level 65. Granted, the other character is an engineer, not a science officer, but that shouldn't really matter.)
Anyone else having this problem? If so, could you please post how you solved it, got around it, etc.?
The last report about this that I could find on this website was from November 2018, so I figured that three months was probably too long and posted this message today. I didn't want to get a warning about necro'ing a three-month-old thread.
