The old 3.8 original

I can probably get the original grim 3.8 project working for you, and send over the project files, so you can do self updates if you still haven't gotten it to work.
Just offering.

That would be cool but I don't even have a compiler so that would just be a waste
Besides the original source code of 3.8 is freely available anyway

The only real problems I'd have with the 3.8++ bot is that anything having to do with items don't work along with packet sniffing and spamming
And that the skills added to the bot is completely ignored since it just does whatever the hell it wants for some reason

That's a bug also from +. You need to Add/Use skillset first. If not applied, it will default to 1234 regardless if there are skills added.
