Game keeps crashing

shazbot182

My game continually crashes after a few turns, usually around turn 4 but sometimes at turn 6. Here is the error I get every time:

Comparison method violates its general contract!
java.lang.IllegalArgumentException: Comparison method violates its general contract!

Why does this always happen, any way to fix?

Hi @shazbot182
What triplea are you using ? The latest stable is "2.5.22294"

Can you post a saved game right before the error happens ? Or even better after it happens if it will let you. If not, just proceed to your normal rd 4 moves and save before it usually happens.

@beelee autosaveBeforeEndTurn.tsvg

sure here it is, it is saved during the AI turn and will crash every time the next phase is loaded. And yeah I am using the latest version.
