negative amount of resources in minig facility

[tilo]

I got (several times already) a negative amount of resources.

Structure Type     Mining facility     
Carbon    Stone    Ice    Iron
490    0    4.422    0
Metals    Gold    Diamond    Credits
4.063    4.037    -978    0

This happens production replication if there ist not enough input.
If I try to withdraw something from this negative amount it is reset to zero.
I'm not sure wether the output is corrected or the negative resources are also added to the
replication output.

Yeah that is a common bug. The negative is treated as zero...so withdraw away
