Describe the Bug
Chain is not using the operations order.
To Reproduce
1/ Make new chain
2/ Add operations
3/ Calculate Chain & export G Code

Expected Behavior
Expect the order to be the same as the operations list in Chains.
(But it seems to use the order in the Operations tab instead)

It exports CutOutRough -> CutOutFine -> Details instead of Details -> CutOutRough -> CutOutFine
