Sonic Resonator Upgrade must keep upgraded battery (Advance battery) instead of downgrade

Sonic Resonator Upgrade must keep upgraded battery (Advance battery) that I have installed instead of downgrade it into basic battery

I don’t think this was ever a thing in Sub1, I doubt they’ll implement it. It would be nice though. But the workaround is just easy - unload the battery before you craft the upgrade. Althogh my forgetful self would def. struggle with that too lol

If you take the battery out before crafting, you get a free basic battery.

Are you saying upgrading a sonic resonator containing an advanced battery into a feedback resonator results in that containing a regular battery instead of an improved one? If so, that’s a bug and does not belong here.
