Supply units disbanding themselves.

Title says it all. Not even sure where to look or check as to why this happened.

I had 1x Large, and 3x small. Today I only have 1 of each.

Any suggestions as to where I can look to see why this happened?

My newspaper has shortages of gasoline noticed, but I have 10's of millions of units of gasoline in stock so idk why its complaining about that

Hi, please share world and country name.

Did you check if you have enough low level workers and medium level managers? All war units indirectly use them as they are needed to fill each weapon type.
