Force players to go in safe house

I've installed a plugin from error 404 to force the players to go to the safe house.
When 3 players have entered the safe house a timer of 120 secs starts.
Then after 120 secs all players outside get killed.
I hope the plugin works as expected.

This plugin seems to have a bug in map c10m5_houseboat.

The counter starts when the map is loaded.
It seems that is detects the door of the start safe house as the end door.
But in this map there is no end door.
The map ends on the boat.

Maybe the same bug happens in other maps too.
Maybe in all maps without a door at the end?

Would be great to get feedback about other maps with this bug.
But like I said, the plugin is disabled at the moment.

Maybe I will add a quick fix for only this map and search the root cause later.
