RTF is a global modification that replaces all towns in the game.

In principle, there is such a mod - BDT, it had a yeti (a demon with its head) and a bank with them, it might be useful there.

Otherwise, we will replace the unfinished yeti with ours and add it to the random generation (by the way, I don't know how this will affect the Random Map Generator, it seems to have its own complex generation schemes).
