The usual question and the answer is so simple: there's people who play the game and those who mess with it and do it so much that they know what they're doing. I tried myself fixing few mods various times (texture issues) but i won't put the effort here (i'd just want to play the game instead of fixing mods) especially when there's already modders that would know what to do and enjoy doing it. If someone cares and can fix it they will, otherwise the thread would just die. If some people care than there's demand and maybe a new modder or whatever will see the bump and get on it. There's people who want to enjoy old mods again and very few of them knows how or are willing to put hands on them, not everybody is a programmer/modder. Yes i understand that seeing a bump on an old mod and it's not a guy that fixed it already is stressfull and apparently ruins your day.
This is a very complex mod. I don't think there are many players out there with the skill to fix it (I don't, that's for sure).
