Continuous Map Descriptors RS View has been known to crash if it tries to read a server mapping that is discontinuous. e.g. Server map 1: N21: 0-31 Server map 2: N21: 32-100 This will panic the FieldServer and crash RS view as the DH+ will attempt to map N21: 0-100 If set up as: Server Map 1: N21: 0-100 No problems are experienced 6.2.
