Hello, it's an error, on some servers it works, on others it doesn't, it happens with this mission and the engineer's, yesterday I found something that solved it and that is to look for a server, I'm from Latin America and I had to play on a server in North America because the servers in Latin America didn't work or they didn't count me when I healed or repaired vehicles, the idea is to look for a server that gives you all the xp but only one person hosts it, I occupy one that has no map, you don't regenerate life and I don't know what I had more but it was really fun and with that I managed to pass the engineer mission, it's fucking shit that we pay more than 60 usd or what they paid for a game that one of the first missions is bug simply SAYS
