If Nexon ever buy ToS rights and code, it will be through Korea, they might remove temporary (or for all they care completely) from west and fix the stuff needed.
But in all honesty, if the game code is really messed like a staff said it is, I doubt Nexon would even be dumb of waste money on a project that was wasted from the start.
To fix the actual stuff, it would be necessary to rework the code from the ground up. Basically remake the whole code again.
Who would waste money and time on that at this point?
One thing that can be happening tho is, IMC is pushing with their belly the main issues while remaking the code to apply in big patches when they are fixed.
And as I said on other posts, I will only believe on the above when they show the results, not through texts without any value to back it up.
