I guess "naked" isn't the right term for it but here's what's happening. For some people like myself if playing online custom lobbies/co-op bot matches sometimes,
the 7.00 bots just load with their base models only without any skins/custom wearables or bots don't load with any wearable items (default/custom ones). So like some have already said here: They have missing body parts because base models don't have all that on every hero. Eg: Invisible tiny, Headless CK/luna/SF/jugger etc.
Playing offline mode bot matches I can recreate this bug easily: The picked hero and bots in offline matches have only their base models. Have no idea what's causing it or how to solve it because I have tried reinstalling steam and Dota + resetting all settings to default on cloud and on PC to no avail. However, there is something interesting to note here: Playing online alone, if you use the start bot match option on main menu the bots will load the wearable items but not in lobbies regardless of where the server is set i.e local or on Dota's servers. Also playing online bot lobbies (alone or with people), picked hero will have wearable items if you have equipped on loadout but not the bots if you have the aforementioned bug when playing offline since it seems in 7.00, bots use the host's wearable items.
I have no idea if it affects everyone or just some people because my friends are too lazy to check it in offline mode even though I asked them to see if they can recreate it.
