Yeah, that makes sense John, I guess I should learn some restraint and stop making some easy upgrades by bypassing the retool process...
I believe the game should at least enforce the locking mechanic before allowing retooling, with no way to unlock. Its not just a cheat, its also very confusing for a starting player that have no way to know a design change will propagate this way. But this must already have been suggested of course heh.
In v4.81, starting the retooling process will lock the selected design. It can still be unlocked but only in SM Mode.
