There seemes to be a bug in the maps KZlv_vaz_ujo_e and kzlv_vaz_ujo_h. FPS Death shows that the button is pressed twice, when in fact it is a bug that appears when the first door is opened (pressed).
This is something i've never seen in a demo before, after checking the demo with 'dem_forcehltv 1' the button is clearly pressed twice eventhough it is not. Thanks to soul|ftw who noticed this bug, and let me express my cencere apology for this mistake (it wont happen again!!).
MepH's demos will of course be added, and the ban will be revoked.
