Hey ! ( Am i gonna post everydays ? )
I had a lil' problem while buying the shield upgrade MK X that gives +20 to shield regen because the serv crashed so i came back on the server and my account had only ~5M so we're okay with the price but ... I had no shield upgrade in my cargo. I checked it twice in all cargo type and then i rage quit'd.
