I have a pretty basic Prop Hunt dedicated server installed on RHEL 6. The Server launches and I can connect just fine. A couple friends of mine will play through a map and everything looks good. When the round limit ends (I have mine set to 4), the map does not change and the round timer goes away. I take a look at the dedicated server console and see the following error:

[ERROR] gamemodes/prophunt/gamemode/round_controller.lua:151: attempt to call method 'EndOfGame' (a nil value)
1. PreRoundStart - gamemodes/prophunt/gamemode/round_controller.lua:151
2. unknown - gamemodes/prophunt/gamemode/round_controller.lua:242

Timer Failed! [Simple][@gamemodes/prophunt/gamemode/round_controller.lua (line 242)]

No googling so far has really helped out with this specific issue. Any pointers here?
