Greetings and thank you for sharing this great work. I have encountered a minor bug when using your extended functions as addition to your assets mod. When interacting with a "door with cardreader" while having any card. It doesn't matter if the card has the right or wrong access level. Instead of playing any sound when interacting with the door the following error is shown:
----
'... ASL _posCreate;

_soundOrigin say3D |# |_randomSound;

[_soundOrigin] spawn {
s...'
Error Undefined variable in expression: _randomsound
File DGF_SCP_EF_FIXES\functions\fnc_buttonSound.sqf..., line 52
----
If I disable your extended functions mod and only use your assets mod the door sound plays correctly. Looks like a possible typo? If you need any more information feel free to get in touch with me.

Hello Flaesher, sorry for late response,

1. Assets mod is not created by me;
2. This fix will be removed soon, since the author of the assets mod has implemented a similar fix to the problem this aimed to solve; it will remove the error.
