I can (semi) repro on a standard install (08049b32b6)
- create invite with an ‘arrive at topic’ value and send via email
- click ‘resend all invites’
The first email had the topic title in the email subject, whereas the second no longer contained that info.
However, on accepting the second invite it did indeed allow my test user to arrive at the designated topic after signing up.
So this may be less of a functional bug and more a ux issue to ensure the resent invite email mirrors the same info as the first in the email subject? (ETA: and email body)
