Index out of bounds randomly

[GodDragoner]

Seems like in the newest version this:
System.IndexOutOfRangeException: Der Index war außerhalb des Arraybereichs.
bei Tease_AI.Form1.SysKeywordClean(String StringClean) in G:\Dario\Tease-AI2\Tease AI\Form1.vb:Zeile 7813.
bei Tease_AI.Form1.PoundClean(String StringClean) in G:\Dario\Tease-AI2\Tease AI\Form1.vb:Zeile 8251.
bei Tease_AI.Form1.Timer1_Tick(Object sender, EventArgs e) in G:\Dario\Tease-AI2\Tease AI\Form1.vb:Zeile 4766.
bei System.Windows.Forms.Timer.OnTick(EventArgs e)
bei Tease_AI.teaseAI_Timer.OnTick(EventArgs e) in G:\Dario\Tease-AI2\Tease AI\Classes\teaseAI_Timer.vb:Zeile 50.
bei System.Windows.Forms.Timer.TimerNativeWindow.WndProc(Message& m)
bei System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Shows up randomly. Any idea why? After that Tease AI won't continue with the text. I know that it seems to have something to do with date difference and basicly a string that looks like #DateDifference[Something], so without a , but because it is occuring randomly I am kinda in the dark rn. Any idea?

#DateDifference[Something] is not correct. It should be #DateDifference["variable","Any of: Second|Minute|Hour|Day|Week|Month|Year"]

Does this help?
