Good day to you all. This will be my first time posting this because it has happened several times every time I update the game.

After I update the game and then import the save file to newer version, I can't craft any equipment. Every time I tried to choose a material, it always come back with blank screen as if I have 0 materials available. Yet I can still craft other items (food, base materials like steel) yet no equipment.
When I tried to use ALT+Tab to see the second window (report window?) it shows this report

SCRIPT ERROR: choosematerial: Invalid get index 'herbs' (on base: 'Dictionary').

                              At: res://gui_modules/Mansion/Scripts/MansionCraftModule.gd:414

At first I thought it is just a normal bug since the game is still in development, however, after several times it happened and I tried to search the bugs report and found no one reporting it, I try to post one and hopefully someone can find a solution.

The issue is that there was an item added to the game called "Herbs" which v5.3 is looking for, you can manually added it in to your save by save editing it.

1.) Finding your save file (ex. autosave.sav) :
　　C:\Users\(Username)\AppData\Roaming\Strive for Power 2\saves

2.) Use a .sav editor, online or app
　　Quick google search of ".save editor"

3.) When editing the save, locate the list of materials close to the bottom of the file:
　　Use Ctrl + F and search "materials": {

4.) Add in "herbs": 0, between "grain" and "ice_crystal" like so:

      "grain": 5297,

      "herbs": 0,

      "ice_crystal": 7,

Once you're done your crafting should work just fine again, hope this helps!
For future updates, it may be similar issues of added materials and such therefore just compare a new save to your old save in terms of materials.

Thanks for the report, we will hopefully fix it on next update

It works like a charm.

Thank you very much for your help.
