They're clearly never going to.
Because it's not possible for new people to show up down the line, who is willing to write scenes for tailcunts (either because they like that kind of stuff, or they are willing to write it for a commission fee)
A couple of questions, if you don't mind, and if it does not derail the thread too much (have not ready every single page in this thread, so not sure how off topic comments are allowed to get)
1: If one or more people are willing to write enough scenes where tailcunts are used down the line, would you consider adding it back in? (they might not have had time to write anything when you offered cash money, or they might not have known about CoC2 when you did)
2: Could it not just have been turned into a tail with a unique description (maybe two, or three variations), but without any tail flags for the game to keep track of, and not have any functions, like some of the tails already in the game, maybe it could serve a function in combat as a way to deal blunt damage?
If number 2 is a possibility, then i might be willing to have a crack at it (granted it's not something i would be able to do overnight), as it seems to be simple enough (for someone like me), when compared to having to write multiple scenes where it's used (I do have ideas for some scenes, and i'm sure i could come up with more. However i know that i would never be able to write them with the quality required)
