[Beta 6] Resource consumption is not calculated correctly - [SOLVED]

No idea if that's something known by masses already, but I've just found out... 

When you're running in negative resource production, its consumption is badly miscalculated. You can see this in Zultar's recent video at 14:46 (https://youtu.be/oWksPtKGz10?t=886). If you watch his water you can see he was only consuming 0.55 water/s but it jumped down way faster. From my tests I kinda felt it was tied to HQ level - the higher the HQ level the worse it gets, but I'm far from being sure. When production=consumption the stockpile goes up and down by the same amount, for example 36-39-36-39 etc... So if any of you felt like you're constantly broke in Beta 6 or accumulate the debt much faster - that might be one reason.
