Im Stuck In A Quest, With No Way To Get Out

Hello there, yesterday i decided to do the quest A Sandy Scandal, i got until the part where the bank got robbed, and i needed to defuse the tnt, which i did, then the robbers ran, it said that i need to blow up the door with the leftover tnt. But i didnt even have an tnt, it didnt give me any, there was no tnt on the ground or something, that made me stuck, then i accidentaly threw my bow in the hopper, i know i can /kill but i'm afraid to do it incase i mess up the quest and i cant go back.

Additional Info:

Won't mess up the quest do /kill

(I would try logging into a different server before you do that first)

 

UPDATE: I did /kill, but now the quest is kinda broken, it still says i shuold explode the door with the leftover tnt

 

You have to kill the bandit leader to get the leftover TNT.
