Hi. I'm using a L4D2 plugin that keeps reporting hundreds of the same error in the log. This:

L 03/07/2020 - 10:36:46: [SM] Exception reported: Entity 3 (3) is invalid
L 03/07/2020 - 10:36:46: [SM] Blaming: lastboss.smx
L 03/07/2020 - 10:36:46: [SM] Call stack trace:
L 03/07/2020 - 10:36:46: [SM]   [0] GetEntDataVector
L 03/07/2020 - 10:36:46: [SM]   [1] Line 903, D:\Steam\steamapps\common\Left 4 Dead 2 Dedicated Server\left4dead2\addons\sourcemod\scripting\lastboss.sp::AddVelocity
L 03/07/2020 - 10:36:46: [SM]   [2] Line 768, D:\Steam\steamapps\common\Left 4 Dead 2 Dedicated Server\left4dead2\addons\sourcemod\scripting\lastboss.sp::JumpingTimer
These are the sections the plugin is complaning about:

public Action:JumpingTimer(Handle:timer)
	if(form_prev == FORMFOUR && idBoss)
		AddVelocity(idBoss, GetConVarFloat(sm_lastboss_jumpheight_forth));

public AddVelocity(client, Float:zSpeed)
	if(g_iVelocity == -1) return;
	new Float:vecVelocity[3];
	GetEntDataVector(client, g_iVelocity, vecVelocity);
	vecVelocity[2] += zSpeed;
	TeleportEntity(client, NULL_VECTOR, NULL_VECTOR, vecVelocity);
How can this be fixed? I would ask in the original thread, but the plugin author hasn't posted anything in the past 9 years.

It's ztar's lastboss: https://forums.alliedmods.net/showthread.php?t=129013

Fast fix may be:
if(form_prev == FORMFOUR && idBoss)
if( form_prev == FORMFOUR && idBoss && idBoss != DEAD && IsClientInGame(idBoss) && GetEntProp(idBoss, Prop_Send, "m_zombieClass") == CLASS_TANK )
BTW, what game do you use it on?

Yes, that's the one. And I use it on both L4Ds. That error is making the logs unnecessarily large. I will try your suggestion now and report back. Thanks.

Well people have been playing fo the past two days and that error hasn't appered again. That seems to have solved it. Thanks Drogakas
