Loading Models

So I’m loading some newer models on an older client using Galkon’s Repacking method.

I add the gzipped files into the index1 folder and call it successfully, log-in and get this:

Exception in thread "Thread-3" java.lang.ArrayIndexOutOfBoundsException: 19047 at Model.method462(Model.java:116) at ItemDef.method201(ItemDef.java:436) at ItemDef.getSprite(ItemDef.java:310) at client.drawInterface(client.java:7885) at client.drawTabArea(client.java:1642) at client.drawGameScreen(client.java:7613) at client.processDrawing(client.java:8455) at RSApplet.run(RSApplet.java:119) at client.run(client.java:4369) at java.lang.Thread.run(Unknown Source)

The ID of the item or model is too high;
19047
