Is there some sort of bug that allows competitors to continue buying from you before you, even after you turn on Internal Sale? I did a little bit of testing after this, and if I turn on internal sale before the product goes to market they can't buy from me, but am un-able to take it off the market - so to speak.
It's not a huge issue, since I could set up the internal sales before allowing a new factory to sell products, but it would be nice if this was fixed just in case I or someone else forgets in the future.
*Side Note: Just in case this helps in your trials of figuring out the problem, this happens in both the factory "Sales" unit as well as the Warehouse "Output" unit.
