TeaPack

Hello,

i had same message while server restarting. If I reloaded plugin after server fully running, i got no errors. So I added one variable and OnEntitySpawned can doing original function only after OnServerInitialized is called. Now no errors while restart :) I think problem is this function is called too early while server startsup.

My changes in InfoPanel.cs (i also write some original code around the new code - for easy diy change):

At begin of the cs file:

[Info("InfoPanel", "Ghosst / Nogrod / TeaPack", "1.0.0")]

#region DefaultConfigs
private static string DefaultFontColor = "1 1 1 1";
public bool startedup = false;
#endregion

In void OnServerInitialized():

if (ActiveCargoships.Count > 0)
{
CheckCargoship();
}
else
{
Cargoship.Refresh(storedData, PlayerPanels);
}
startedup = true;
}

And finally in OnEntitySpawned:

private void OnEntitySpawned(BaseEntity Entity)
{
if (startedup == false) return;
if (Entity == null) return;

I keep getting errors about wrong symbols.

Can someone just share the whole .cs file so we dont have to go through this much trouble? I know "we dont allow for random plugin versions blabla" but the author hasnt updated this so he doesnt care so why go through all the trouble if it can be easily solved
