flawed signal data problem :(

Yes. That's exactly what I meant. You used to be able to purchase those modules. Now that's no longer possible using cantina energy.

it's available you can't search for signal data currently and find it in cantina, you need to go to campaigns and then go to the 2 cantina nodes that have the signal data

I think he meant flawed signal data was not farmable anymore in a cantina node. I farm that everyday using cantina energy towards my dailies but cannot today, it is not available.

Did use a bot to translate the post into English? It makes no sense. Canteen (presumably you mean cantina) energy "currency"? What?

Cantina energy is still used to farm signal data. Cantina tokens (the round orange ones that you get for hitting cantina nodes) never had an option to buy signal data. 

Make your post make sense, then maybe we can find an explanation for whatever your problem is.
