a small spoiler for the new mod (if there are no problems with this, of course)
I ran with this script and this is what I can say. It works, the level is accumulated, points are given for the achievement. Of the minuses, missing prices on the player's items. If you have something in the bank, then first you have to take it for yourself, install the script and put it back, otherwise the game will break when you try to take an item in the bank. More bugs were not noticed. Second, this script affects not only the level, and it is a problem, I can not fix it I can not programmers and nothing in it do not understand, but there may be able to change the script, or write your script on this example, so it affected only the level, and nothing more?
