NEW UPDATE Plutonium r1749

We have just released a new update for Plutonium. Changelog:
* Fixed issues with various maps on IW5 (for example, Black box & Test map)
* Fixed issues with Verruckt and Nacht on T4 zombie servers.

My T4 issues are gone, T6 still has it's 'False Heartbeat' moments but something has stopped it from being a constant issue. Love ya Pluto devs

Same issue, no fix known. Replying to hopefully add traction for it to be fixed

I personally host 4 Multiplayer servers here in Australia, but I don't think there's any other regular ones. I know there's a few other Zombies servers apart from mine but no other Multiplayer to my knowledge.
