Current Behavior

Hi, after upgrading to the actual version 5.66.7 under Mac all my configured pathes in all (!) effects didn't work anymore.
After editing all effects and selecting the source again (same path as before) and saving, it worked.

But, I don't get a dynamic path to work, its:

/Users/xxxxx/Documents/stream/$lowercase[$arg[1]].png (means after entering "!command WhatEver" in chat it should show /Users/xxxxx/Documents/stream/whatever.png

I also pasted it in the "log message" effect, to see what Firebot does -> its the correct path. the image exists.
But it won't show on overlay, I only see a small "missing file" icon.

Is this maybe an security issue? but Firebot still allows entering $arg in this dynamic path field.

Happy for every suggestion, thanks!

Expected Behavior

find given path and work with it in the given effect (show, play, animate, ...)

Steps To Reproduce

2. add "show image/gif" effect
3. edit file path to /your/path/to/$lowercase[$arg[1]].png
4. enter !command yourImage in chat
5. should show /your/path/to/yourimage.png

Version
