As per the tread title I've had this happen twice now. I now have two static HK-47's on Dantooine. One by the Jedi Enclave and one by the landing port.
The interrogation cutscene triggered fine and the quest updated so there's no issue there, but I'm now stuck with extra HK's.
I'm using the Steam version of TSL with v1.8.3 of TSLRCM. Mods are largely texture mods, with a few uti tweaks (slightly cheaty weapons).
I did a search on the forums and only found one other thread describing the same issue (http://deadlystream.com/forum/topic/2501-hk-47-bug-182/). Unfortunately the solution presented in that thread wasn't very clear, something about switching out the killblaster for another weapon.
Is there anyway to get rid of those extra HK's? Any help would be greatly appreciated.
