Mod works OK right after installing, but when I load a save all functions cease to work - hotkeys don't do anything, profiles do not swap, even pressing mod button does not do anything.

Also it causes ~1 second freeze once I enter a vehicle.

Updated, should work, but you need a save where the character is NOT in the exotrain.

Just tried it, and get an error when entering a vehicle (Jet from the Aircraft mod):

Error while running event on_player_driving_changed_state (ID 26)
exoman/control.lua:935: attempt to call global 'getExoTrain' (a nil value)

Could you make a version withjout exotrain at all? It seems it is the primary reason for all the bugs, and I personally don't see any use for this function. In fact I only use this mod for the roboport/exoskelleton turning hotkeys, and cutting gimmicks like flying boots or exotrain would improve performance an/or reliability.

Fixed. As for removing the exotrain, i'm afraid that's a no, but i'll make a proper version 0.0.3 soon.
