Whenever I try to install endo on a mech, I get the "cannot create work order" message. I've tried selling all 20 of them, then buying them back, but if a mech doesn't come with it installed, I am unable to use it at all. No issues with ferro fibrous or any of the other items with dynamic slots, only endo. Any idea what might be causing that? I just tried using Clan endo and have the same issue. Only structural component that works is the composite one.
