[BUG] Xteas.json file missing starting in 2024-11-27-rev227

[cbartram]

• I am using the latest version of the exporter

Bug description

The cache fails to load because of a missing xteas.json file that should come pre-packaged with the cache from https://archive.runestats.com

This makes revisions newer than 2024-11-27-rev227 unloadable.

Steps to reproduce

1. Open env exporter
2. Load the March 5th 2025 cache and see the error

Expected behavior

The cache loads as normal

Is this something you might be able to contribute a fix for?

Possibly, detecting when the xteas.json file is missing from the runestats cache is trivial. The problem is finding the cache decryption keys that work with this package.

https://archive.openrs2.org/ seems promising however, after trying their xteas.json file with the 2025-03-05 revision from archive.runestats.com a buffer underflow exception is thrown:

Exception in thread "AWT-EventQueue-0" java.nio.BufferUnderflowException

	at java.base/java.nio.HeapByteBuffer.get(HeapByteBuffer.java:165)

Same issue when using both files (cache + xteas) from openrs2.org. I need to investigate more on how the cache is being loaded and I'm not super familiar with Kotlin but I'm great at Java so should be able to pick it up quick.

Edit: Upon further investigation there aren't problems loading xteas.json file(s) from openrs2. The issues I am encountering is that the OverlayLoader data size is always 0 on newer caches. Indexes like 8 for sprites and 5 for maps don't seem to be present in the cache at all oddly enough throwing errors while loading sprites etc...
