QuoteDisplay MoreFear's Update of Trap's Progressive Stash updated to 3.9
For the update, I changed any reference of api to spt, and update the version number. Seems to work fine for me when I tested the upgrades from a fresh profile.
Probably best with a Standard or Zero to Hero profile since those will start your stash at level 1.
I also implemented some of the changes from Softcore and made the stash upgrades cost less rubles and require 1 less trader level. The stash sizes have also been changed to the actual tarkov sizes. If you want to change any of that, the numbers are in the config. Go hog wild!
Then I removed any of the code affecting secure containers so you can use this in combination with Leaves's Progressive Container
There's still some leftover values in the config, these shouldn't affect or do anything to your server.
