Vanishing barrels from refinery

[Driver]

I have an oil refinery setup with a max level efficiency module in it (50% cost reduction). If I order a single batch of epoxy it costs 2 barrels of petroleum and I get 2 epoxy and 2 empty barrels.

So far, so good.

However, if I order 10 batches of epoxy it costs me 19 barrels (Lavish workstation bonus of -5% materials means 19 instead of 20 barrels) and I get 20 epoxy but only 15 empty barrels. Where did the other 4 go? It means that if I don't want to lose any barrels I have to order each item I want one at a time, which is annoying to say the least as I can only set up 5 orders at any one time.

Is this intentional or a bug/oversight?

I discovered the same problem on my side. At the end I have modified the recipe in the game files to solve it. (needed and produced barrels are now equal and are now both unaffected from modules)

Known issue, will be fixed.

How did you do this ?

[snap81]

was this ever fixed?

[Falconius]

not yet but with max level and oil module you can craft 3 at a time without loosing barrels

It was, but 25% of barrels are now lost intentionally to wear and tear.
