Have you tried on TestLive? It may take some time to figure out whether or not it is working there, but in the previous TL patch a few improvements were made to the Purge system. Any feedback is appreciated by the developers. In future TL patches more adjustments will be made.
If you want to try out TestLive, you may want to read How to Access TestLive (be sure to make a backup and maybe you want to try my reply on Testlive Questions, because it’s kinda useful for some players.)
FYI: Purges are one of the main focuses right now, along with the Pets update and severl QoL enhancements.
