Random ArrayIndexOutOfBoundsException when getting messages

Hi, I'm sometimes getting the following stacktrace error in a function of mine:

Is there anything you guys can change about that? I looked a bit into it and it seems like that's not really an issue in Kord, but I'm not too sure

I'm simply using val message = textChannel.messages.firstOrNull { it.author?.isSelf() == true } on textChannel: GuildMessageChannel if you guys need more examples for this stacktrace lmk - Im getting that error at random times ever since I implemented it (but it seemed like a random 1/100 chance, so I ignored it for a while)

@Taubsie an off-by-one, haven't seen that yet. Which version?
