It seems like radiant quests are unlimiited, but Tom seems to have run out of MILAs for me. He still has 9 in his inventory though. I did get the ballistic weave so maybe that's as fas as it goes. For the most part, radiant quests are just boring filler, but these I enjoyed because there was some challenge locating the perches.

How many of them have you done? I believe there are 11 total MILA quests. I finished them and he still had some in his inventory too, so I don't know what the deal with that is. I never tried taking one from his inventory though. Maybe if you do another MILA quest unlocks?

I was glad that quest chain did come to end. So it wasnt't pointless setting them up.

I did at least 9, so yeah.

There are limited high places Tinker Tom can place them, so it will run out eventually.
