Monster seeing through walls..??

[iLucian]

You mean the terror sound goes on and on, and he runs towards you?

Please check the following:

- Can you move through the walls as well?
Even if you can't, please check that you don't have a yourmapname.cache file lying somewhere.
If you do, please delete it. Don't want those to be there when you're editting.

- Do you have the scriptline ShowEnemyPlayerPosition in your script?
If so, delete it. Or put two backslashes (//) behind it, to make it inactive.

Neither of those are occuring, still do not know what the problem is.
