Hey there, I'm getting this error when opening the Q menu in singleplayer:

[Advanced Duplicator 2] lua/advdupe2/file_browser.lua:1129: attempt to index a nil value
1. UpdateClientFiles - lua/advdupe2/file_browser.lua:1129

Timer Failed! [Simple][@lua/weapons/gmod_tool/stools/advdupe2.lua (line 1517)]

1. unknown - lua/advdupe2/file_browser.lua:1058 (x2)

The error doesn't load any dupes, and renders the addon unusable. Can't even bring up the tool to copy models, either.
Would anyone happen to know what error this is, and whether there's a fix or workaround for this issue?
