Trailer will not accept liquids constantly. trying to load from the oil rig and it will load about 50 some liters then cut off.

So, with the most recent update on 22nd of november i found out, that the pumps from any oil rig stop working after a while. And i found out, what it is: air. Yes, air's getting in, i had opened the top lids of that trailer and air shot out with enormous pressure, this affects every vehicle before the pressure update, that has a tank, that contains liquids. Can also be the reason, why the oil pipeline's not working, because there's air in the system, even when the container is sealed off, it somehow gets in.
