Not a big deal, or anything requiring further support, but an observation worth noting nonetheless:
If a dynamic target is set between 2 steps and one such step is removed from HTTP traffic, rather than being able to edit the target to reflect a new destination step (or rather than the target information simply passing to step taking the place of the deleted step in the HTTP order), the target destination defaults to zero and any attempt to edit that traffic or the dynamic target further results in the application crashing.
Also of note, the reason that this has been an issue, is that deleted traffic seems to be reappearing on application close-->reopen, even when the traffic is saved (with or without the crashing behavior).
Hope this helps! Thanks.
