AntiMsgHack and UTPure (wat?).
I'll see what i can do about this.

[Higor]

AntiMsgHack:

Assumes all pawns sending messages are PlayerPawns.
When a sgBuilding about to be destructed sends a message... boom, fails and a second self destruct command is issue, plus a ban on an empty IP is issued.
Needs instant fix.

Pure isn't running, and anti message hack, well that's self explanatory lol. it's to prevent message hackers

--- Updated ---

In that case, just decompile anti msg hack and add an exception for siegegi?

[Higor]

UTPure:

Simply blocks everything coming from a Pawn...
Are you fucking kidding me?

--- Updated ---

Pawns are totally unable to send messages, this clearly hurts monster based games.
I can fix AntiMsgHack, I already retrieved it, but it pains me to see that UTPure made such a mistake (not differ from any pawn and PlayerPawns).

[SAM]

I have the source for Pure if you'd like it....

[Higor]

Already checked the UTPure sources.

The only way out of this is calling > Level.Game.MessageMutator.MutatorBroadcastLocalize dMessage(Self, P, Message, Switch, RelatedPRI_1, RelatedPRI_2, OptionalObject) replacing SELF with NONE on the sgBuildings.
This won't allow other mods to figure out if a sgBuilding is broadcasting a message, but it's the only way with something as big as Pure.

[SAM]

But pure isn't running Higor so it shouldn't be doing anything anyway!

That's your next job. Make siege compatible/work with pure.

[Keith]

@Higor do you have an idea why Teamsay spec messages are corrupted?

[Higor]

Well, it's one of those mutators that's messing those up, I'll review them one by one I guess.

[SAM]

I know which one it is. AutoPause.
