Bug Repairing sails resetting colour rigged sails back

[Symban]

As title says, in my current GoF 1.2 game when I repair my ship the colour rigging is resetting back to white default *sometimes*. Thing is once it is happening I can not go around it by loading back a save before repair. Any loaded game still resets sails back one repaired.

It is a pretty minor issue, but wanted to share, and would appreciate if anyone has a solution. Thanks
