I've seen maps with four rows of 6.
on each side, and an awp at either end, that's 50.
So, no, there's something you're doing wrong.
I take it you're following this tutorial?:
http://cariad.co.za/twhl/tutorial.php?id=87If not, do so, and if you are, then you must be doing somethign wrong, armoury_entities are the most docile in teh game, you set teh weapon, you set the amount (count) and then you compile. There's not alot that can go wrong.
I'm not sure if teh entites are allowed to see too many of each other, so .. is there any division between the spawn points of CT and T and are the weapons all visible from one point?
Otehr than that, I'm not sure what's wrong, try uploading to the vault, maybe 7th could have a look, as I'm at work until 5, if no-one can, I'll fix it up for you then.
