Disabling Purchases of Type 3 Chi-Nu Kai

As announced earlier, Update 3.0 increased the profitability of certain vehicles. However, there was an error in the profitability calculations for the Type 3 Chi-Nu Kai. As a result, the vehicle is now more profitable than we originally intended.

We don't want to roll back changes or weaken the tank, because that wouldn't be fair to players who already purchased it. Instead, we're disabling the option to purchase the tank with Gold in the tech tree. If a player attempts to purchase it, an error message is displayed.

As for the future of the Chi-Nu Kai, we'll be keeping our eyes on its performance from here on out and any further decisions will be based on analyzing that data.
