The missing two TLE sets have now been published by 18SPCS.
The reason it took so long is probably that it was hard to detect
all three 1U Cubesats with a distance between them of only a few
kilometers. Since they are now less than 2 seconds apart, it is not
yet possible to determine which one is AO 91.
So AO 91 is either object 43016, 43017 or 43018. For the time being
you can use any of the TLE sets for these three objects.
