It should happen on every attach and routing area update. E.g. if
you have periodic updating enabled in the NITB you should see this
behavior (bug) every time.

I intend to look at it during wednesday. My current trial will be
to change code in here[1]. When the TLLI is changing try to find other
TBFs (e.g. if we ever support multiple tbf assignment) and update
the TLLI as well.

I would also say that if the tlli is changed, it is valid. So the
separate "mark valid" function is probably not needed. But I need
to modify the code in bts.cpp for that.
