Same issue here- all oil quickly drained from all deposits on map once opened a save recently

Here's a thought that could fix the issue, though i do not know if it is possible with the current pipe mod from VE. Maybe allow us to pipe oil from adjacent tiles, as 1 map isn't much fuel, but setting up oil pumping on up to 6 adjacent tiles would allow for a lot more oil production with the tradeoff being it has to be maintained and counts as a colony for all in game purposes.

The piping idea is solely as a way to prevent you from having to spend the steel to shoot pods, or run caravans as this mod creates such a volume of oil both methods aren't very practical.

I have the same bug, would be nice if you could look into it.
