The function disableCollateral of OverlayV1Mothership.sol doesnt set collateralActive\[\_collateral] = false;
But it does revoke the roles.
Now enableCollateral  can never be used because collateralActive\[\_collateral] ==true  and it will never pass the second require.
So you can never grant the roles again.
Note: enableCollateral also doesnt set collateralActive\[\_collateral] = true

In function enableCollateral() add the following (after the require):
collateralActive\[\_collateral] = true;
In function disableCollateral add the following (after the require):
collateralActive\[\_collateral] = false;
