I updated from the previous version of SPT to 3.7.0 as soon as SPT realism mod and the rest were updated. I was in the middle of the scrap metal task, having marked two of the three tanks on shoreline before i made a new seperate SPT folder and installed SPT to that with the installer. The objectives state i need to mark the third tank, and i have been around to mark the two others, the one in the village and the one at the northwest bunker, but the third on the bridge by the power station does not show a prompt to place a marker, regardless if the marker is in my secure container or in my inventory.
Tried to buy a new marker, doesn't help, the other two tanks are also not possible to interact with. Not sure what is causing this, but if there was some way to force completion of the quest that would be a lot easier than to figure out why it's not working..
