Corporate Production Contracts

Recently my common market changed the requirements for products offered on the market. Trying to manage my Enterprise all at once didn't work - offered 45% at the bottom, and it offered 100% or more for some of the corporations.

Decided to manually input the numbers, bringing market committment down to 45% - the requirement - and worked fine until the game decided to arbitrarily raise quite a few of them

Any advice on how to manage this? Do I have to go through every corporation, break out a calculator, and input the numbers there? I really don't want to spend all of my game time typing.

Please help, as this is getting to be extremely unfun.

Problem solved - left the common market.

I've had to deal with bugs, glitches, being shutting out of chat and forums when starting, and had to rely on outdated documentation - any more of this and hopefully someone will purchase my enterprise and countries with gold coins in stock for 1 gold coin.

PS - going through them individually didn't help. Worked fine for 1 corporation, then jacked the numbers over 100 % committment for more of them. And reset the first one when I did the second.

Ignore the above please.

My apologies to any readers for being an "arsehat".
