While Take Two's action is completely unacceptable, I think OpenIV closed modding policy is partly the problem here. Almost everyone is depending on one tool don't you think? We don't have enough documentation about the files and resources because OpenIV don't seem to bother sharing with us.
I'm hoping it's all just some big crazy misunderstanding...
I think NTAuthority is right, closed source modding is not helping the community at all.
Let us serve this as a reminder, and we hope that in the future modders will not repeat this mistake :
