no, you should be good, so long as you save your game file after removing the, <include ref="name_of_library_file" /> , code line from your game file code.
Alex designed the quest engine so that it'll load up that library file's contents into your game, but not into the game file itself.
In fact, quest's "built-in" (core coding) is a library file itself:
<include ref="Core.aslx" />
and the default (english) language file:
<include ref="English.aslx" />
which you can, by the way, change to denmark language (I'm sure it's available, hopefully, lol).
can you spot the two default "built-in" library files in the new game coding below?
<asl version="540">
<include ref="English.aslx" />
<include ref="Core.aslx" />
<game name="Testing Game Stuff">
<gameid>d83ba5bb-2e3c-4f31-80c9-3e88a2dc082c</gameid>
<version>1.0</version>
<firstpublished>2013</firstpublished>
</game>
<object name="room">
<inherit name="editor_room" />
<object name="player">
<inherit name="editor_object" />
<inherit name="editor_player" />
</object>
</object>
</asl>
if you're a gamer, think of a library file as a "patch" or "xpac" or "mod" that is used along with your game file for creating and~or playing your game, and thus your game file itself remains unchanged, making it very easy to stop the library file's contents not being used anymore, by simply removing the code line that causes it to be used along with your game file's contents for creating or playing your game, should you not want to use the library file anymore.

If your equip function isn't special (doesn't do anything extra), you can remove it, and then hopefully, Pertex' library will work.

Do you know coding~programming? If you're just new to quest, but not to coding~programming, you should be able to learn it quickly, as it's really user~friendly. If you're new to coding~programming, quest is very noob~friendly in learning to use it's coding too. If interested, I can help you learn to work with quest's coding, as I was a total noob with coding, and have learned quite a lot after ~ a year, though I'm still no where near Jayna, Pertex, Sgreig, Pixie, Chase, Levicki, and etc (sorry if I left any of you off the list, lol).
