Server error when trying to change (apply different) experimental effect to shield booster

[operant]

Changing shield booster from thermo to supercapacitor gives server error.

Tried relogging. Seems to be a consistent error.

Laksak.
Shield booster already G5. Cheung does only G3.

That seems to be intended. Gotta stay below g4, before applying the exp. or make the full trip out to the g5ers.

I had the same thing with my G5 Efficient Beams.
I wanted to change the secondary at The Dweller, but he only does beam lasers up to G3. I had the same issue you have.
I went to Broo Tarquin who does G5 Beams, no problems.

So I would have to guess that it is working as intended.

Guessed this might be the case.
Would have expected a different message.
(Make no game-logic sense, other than 'the grind'.).
