Before the new DLC patch we used the forge to melting metals (same as lots of times), after the patch our industrial forge was ready with ingots, but the storage counter is bad.
When the forge is empty, than show -30/60
when I try to put metals inside the counter grows, -29/60, -28/60, -27/60, etc
when we reach the full storage than the forge counter show 30/60
BUT we can put new ones inside, 31/60, 32/60, etc... up to 60/60, but really 90/60 are inside.
actual patch version: v285.106
