I decided to log into two accounts simultaneously to earn more EC during "Tour The Galaxy" - I had never done it before so I decided to give it a whirl. Both accounts were logged into on the same PC and both characters were part of the same fleet.
Anyway, got to the end of the tour and walked both characters over to the Fleet Bank. I deposited my first characters EC and all was good. I then deposited my second characters EC and it didn't add to the Fleet Bank total even though it had registered in the Storage Log. I had the Fleet Bank on screen for both characters to view the changes but the totals didn't budge.
