command buffer Version 2.1

Hope that helps, No error's with either of these 2 plugins disabled.... Thank you.

Hi, some news on the error. I've seen something similar over the years, errors reporting invalid entity (something else too I forget) and random errors for a bunch of plugins none of which makes sense. Here could be the cause of the problem:

Quote:
Peace-Maker: dhooks has to be recompiled against sourcemod 1.10 to be run on it
Peace-Maker: so the normal dhooks download is incompatible with sourcemod 1.10
Peace-Maker: that's been an issue for a while if you read the last few posts of the dhooks thread
I would suggest trying the latest stable sourcemod version 1.9 instead of the beta, or recompiling dHooks with SM 1.10.

I recompiled dHooks with SM 1.10
made no difference
I have to use SM 1.10
Because supertanks ++ don't work on stable builds.
Thanks for your help Silvers

Your problem looks like there is not good enough checks for the entities

[SM] Exception reported: Entity 200 (200) is not a valid entity
As you seem to have the old code on Supertanks++ i can't really help you following the stack with the current source code, either update to latest and trigger the error again maybe crasher has fixed this?

This is probs not buffer overflow fixer's fault.

I tried the newest supertanks++ and mutanttanks
But no matter what i try they wont read the difficulty configs
Tried removing all plugins not needed But super/mutant tanks still not read it's configs on difficulty
All the previous versions of supertanks++ i have used the difficulty configs worked.
I also don't think command buffer is the issue Just trying to find a fix.
Thank you Lux

If Buffer Overflow Fixer doesn't help you to force reading correct values from cfg, try to use it together with ConVar Anomaly Fixer.
I don't know an exact reason, but, some servers reset ALL ConVars to its defaults (and totally ignore server.cfg and other cfgs) on round start regardless of whether "Buffer Overflow Fixer" installed or not. I think it's some kind another problem this plugin is not initially intended to fix. I could be wrong, of course. That fact is even forced me to update my own plugin, because OnAutoConfigsBuffered() was not enough to fix that problem, so I added additional re-fix on "round_start" event.

What is mean "difficulty configs"? Some console variable?
You changed it in cfg and it is not applyed in game?
Did you try manually change it in game using:
Code:
sm_cvar name_of_cvar "new_value"
to see the previous (old) value to ensure that cvar has incorrect value?

This sounds like a problem with supertanks plugin, not mine.

I managed to make windows L4D2 buffer overflow with commands by executing 50+ in one frame. So the plugins useful for that too.
