Tacvi corpse dragging crashing zone

[Uleat]

I just added a safety check in Client::DraggedCorpses() to the DraggedCorpses list iteration.

Please post back if this fixes the issue.


(It looks like the targeting code might have been setting up a null mob condition and causing an issue in DraggedCorpses..I haven't followed this
through..but, a nullptr reference @ DraggedCorpses.back() would cause a list.erase() and then a ++iterator..which is UB and most likely the cause
of the EXCEPTION.)
