A recent change in TF2 bans the use of custom player attachments.
Attachments are used by some server plug-ins to create new gameplay modes and ideas.
Plug-ins such as PropHunt, TF2Items, EquipmentManager relied on player attachments in order to become valuable plug-ins to the TF2 Community.
Please invite friends who you think may be concerned about TF2 modifications.
