I'm not getting a huge exception dump. In 32 bit 0.90 it seems to work perfectly. On that, I wish mean thrust could be set lower, or just be variable based on the attitude change needs. On my shuttle the CoM eventually shifts to far for the mod to handle without breaking mean thrust, it would have to almost completely shut off one engine. Edit: or it seems sensitivity does not work they way I wish it would. Putting it to max and it does not throttle a 2 engine system very much, never more than a 10% difference. This is an amazing mod none the less, I wish you would take the reigns back or someone would pick it up.
