Sorry, I got stuck again. There's a glitch in the DIY VI Repair room. I had 14 trinkets at that point (including THAT one, yes), and all that happened is it said "Hm" when I used the PS terminal, and nothing happened when I used the T7 terminal.
Ah, got it, looking through the script - it seems that the Polar Dimension PS script "trinketcheckbonus" is faulty. It fails to allow for the possibility of getting that bonus trinket before going to the Polar PS for the first time. An extra line in that script is needed: ifflag(39,diyvirepair)
I think, anyway. That looks like it might fix the problem. Otherwise, I think you have to wait until you've activated all power sources before going for the bonus trinket, maybe?
Spoiler: Oh, by the way, I cheated. Sorry! I noticed something in the scripts about 21 and I knew it was nothing to do with the one in the bonus area (that's unobtainable), so I found a bonus text string. I didn't know which area it was for, though, but I tried it in each area until I found it.
