Context.bin in the main OFP directory seems to record the /Users information, any errors encountered during play or in the editor, among other things. Also, as you said unnamed it keeps a record of the last time flashpoint was run and isn't needed to play on single player RES. I don't play online due to an unreliable connection so I can't test to see if it is checked by a server. Does anyone know if there is more to the context.bin file?
