Generating a master ticket from invite code claim occasionally produces an incorrect result

[tiller-tolbus]

I've used Bridge to create a couple dozen master tickets from an invite code generated by a star, and on two occasions I claimed an invite only to download a master ticket that was invalid. In at least one case, the passport zip downloaded contained a correct management proxy but an incorrect master ticket.

I've attached an invalid master ticket for a planet ~ronmeb-divlev. It was generated from Bridge on 22/1/23, as shown in the image. The master ticket claims to represent the ownership address 0x 4AFA bfF8 FAF9 374 b111 83Ce F215 Fe08 9c62 166f. If you look at https://network.urbit.org/~ronmeb-divlev, you can see that this address has never owned ~ronmeb-divlev.

In both cases where this issue occurred, I was able to simply re-use the invite code generated from the sponsor star and generate a correct master ticket.
