Hello!
I found my ship currency dropping each day, through I haven’t spent it for a long time: I have almost every ship maxed. I clearly remember I had 19mil credits.
Yesterday (March 27, 2018) I noticed I had 9,5 mil credits, today (March 28,2018) only 8,5.
Can you solve it please?

I too have this issue. I haven't used my credits in a bit and one day I noticed my credits drop from over 8 mil down to over 6. Today I login and I'm down to 4mil. But yet I'm not using any of it.
