The spare SMES on Marathon are wired to the output side of the main SMES bank and to absolutely nothing else. Which would be fine as some sort of recharging station, if you had taken them out to anchor them over the main HV network for extra power temporarily or something along those lines, except for the fact that these SMES start empty:
This effectively means they are providing no power to the station and are actively taking away from the limited power, and therefore set-up time, you have at roundstart
Nobody is going to notice this and unanchor them
Unrelated to the main issue but on the same map so I might as well mention it, there’s 3 pipes outside of telecomms that seem to lead nowhere
