Tried trading the lantern bomb to the supplies but it isn't accepting the trade. Tried destroying the box and waiting for a respawn. it seems to be stuck.
Are you sure you have not mistakenly used a lantern? I just did them on Mischief for 6 characters and had no issues.
Can you initiate a trade with any npc? If not, then that trade window might be hidden behind your inventory window. If it's a problem with targeting the crate, you could try the following: 1) use the command /tar kobold_siege 2) put the lantern on your cursor (The order of 1 and 2 don't matter) 3) use the command /usetarget That should open the npc trade window.
