This in P3Dv4 but should be regardless of platform. There are no taxi signs in and around the East Cargo area. For example, last sign on Taxi NB heading East is at NP and intersection of FH, NP and EE has no signage. No signs at all EA, EB, EC, ED or EE. In reality they exist, and just confirmed on Google Earth they are actually there. I haven't checked West of 15R/33L along WC but everywhere else seems to have correct signage.
