the episode with that device that wipes out an enemy force by sacrificing a human life with an energy wave, they dint know to fix that tech because regressed it over centuries. and the other one where sg1 encountered a ppl living under a shield-dome that was losing power-integrity, they dint know how to fix it, same thing they purposely regressed it.
i’d say the shield dome was less they didn’t know how to fix it: they knew perfectly well how to fix it and actively maintained the system, but the system rewrote their memory so they didn’t know anything was wrong
