Yeah, fixes should always we retroactive..whats that please for a fix, that forces you to make a complete new game, just to get rid of something so small like this bug, when it could have been fixed also retroactively through adding of a little new quest that lets Roach die and lets Geralt get a new horse 8which will be named again Roahc as he names all his horses Roach, he said that by himself)
By killing Roach through a new quest, that could be the retroactive opportunity to make sure, that the corrupted Roach Game files get removed from the game and replaced with a new Roach Data File, that replaces the old one, that is optimized for the whole game including the expansiions, because these missing tail bugs started just when the expansions got added, because obviously the roach data file of the vanilla game has some kind of problems with the expansions I guess
In that little quest they could add then also the option to give the players the chance to decide which colors ect. the next Roach should have for those people which may eventually prefer rather to ride on a white or a black horse instead on a brown one.
that kind of new quest could be as simply a new horse race in which you get interrupted by a huge monster suddenly attacking you out of surprise and hitting roach in such a way, that he doesnt survive that attack so that you need to get a new horse and due to you having won for that dwarf in Novigrad whos part of the undergrounds which name I don't know in english (lol..Slasher/ Hacker eventually too? dunno) he could do you a favor by giftign you a new horse therefore that you have won for him a race in the past as he hears what happened to you in that race so he invites you to go meeet him at Vegelbuds, where he gifts you a new horse of choice where you have then several different horses with different looks to choose from which one you want to have as new roach to bring the last race to an end that you have started, before you got interrupted in midsts of the race.
Its a single quest, that could work as retroactive solution for everyone and i think, making a single quest isn't too much effort to ask for getting developed as part of a larger patch which we will get to see most liikely the time around when CDPR brigns out their GOTY edition of the game.
PS: I shouldn#t complain much ,cause personalyl im only affected with this on Velen, everywhere else is everythign fine, but it would be kind of dumb to be forced to make a new game, just to get somethign liek this fixed.
The only point that keeps me chilled about this fact is only, because I haven't made so far a NG+ game, so soonr or later I will make a new game through this anyways.. so my "fix" will come in basicalyl "naturally" the moment I do my NG+ game
However, i feel sorry for all those people, which are runnign already a NG+ game, are really far into it already and are affected by that bug
