Thank You Very Much For help i was busy so i have a late reply here is the objective and a screenshot
Thank you for providing the photos. I also apologize for the late reply.
After getting the gas, Ana suddenly appears and tells me to deliver the gas I got to the guy. I don't remember exactly what happened after that, but I think "Objective" was changed from the one in the picture. But I can't get the gasoline, and the "Objective" is still the same as in the picture. If so, it must be a bug.
However, most bugs in this game can be fixed by restarting the game, so as I mentioned in my previous answer, I would recommend saving the game, quitting, and restarting.
I am not the developer or customer support for this game, so I don't know how to handle this.
I think the person near the light blue truck in the "Rast Area" (sorry if I misspelled it) is the person to give it to, so try talking to him. If you still don't seem to be making much progress, you can wait here for a response from the developer.
If he is in "Las Diosas" (sorry if I spelled it wrong) and not in the rest area, you can get clips and such from the shop and an electricity meter from the graveyard.
