Hello again. The resource bar change is very nice, thanks. I started a new save to try out the new autobuyers as well, they seem good so far.
Found a little bug with the new number formatting.
Also, when I get the problem with the BACK button disappearing in upgrade menus, it prints the following exception to my console:
**SCRIPT ERROR**: Invalid call. Nonexistent function 'queue_free' in base 'GDScriptFunctionState'.
At: res://Scripts/Root.gdc:3912:_root.b_tabkey() - Invalid call. Nonexistent function 'queue_free' in base 'GDScriptFunctionState'.
Not sure if you already saw that or if it helps at all but figured I'd mention it.
