Summary​

New Save Files After Patch Appear Partially Compressed – Slow Load Times & PDX-Unlimiter Fails

Description​

I’ve encountered a persistent issue with Crusader Kings III since the latest patch involving brand new non-Ironman save files (not legacy saves). The problem presents as follows:

Save files created after the latest update are unusually large

Load times are excessively long, even with minimal in-game progress

Manual and autosaves feel sluggish and sometimes cause temporary freezes

PDX-Unlimiter cannot read or parse these new save files, throwing an error

When importing one of these new saves into PDX-Unlimiter, I get:

“The import of the selected savegames has finished. However, there have been some issues with the savegames listed below: autosave_exit: null (error)”

And the Java exception logged is:
java.lang.UnsupportedOperationException
at com.crschnick.pdxu.io.node.SimpleArrayNode.forEach...
This suggests that the current save format or compression structure might be malformed or incompatible — even though the save was generated after the latest patch.

Steps to reproduce​

Steps to Reproduce:

Start a new non-Ironman campaign using the most recent CK3 build (April 2025).

Play for a short time and create a manual save.

Exit the game and try to load the save again — observe increased load time.

Attempt to open the save file in PDX-Unlimiter.

Receive the autosave_exit: null (error) and Java exception.
