I tried re-installing the mod and everything was back to normal. So I went into node edit using "exec node_edit" and created some nodes for a map, then typed "ge_node_save" to save the nodes, the bots appeared on the map with "AI DISABLED" appearing on the screen and I was unable to shoot my weapon again, so I tried loading another map and same thing, I can no longer shoot my weapon and can't find any way to fix the issue without re-installing the mod. If anyone can resolve my issue it would be very much appreciated.
UPDATE: It would appear my Xbox 360 Controller functions fine, I can shoot and play OK, but my mouse buttons are still in Node Placement Mode, even though the engine isn't.
