@lanceal: It looks like you're creating an endless loop in the last event.
Indeed, recent updates in C2 made it so the event call now allows for this "type of issue".
You're generating a hash, and it triggers the event that checks when hashes are generated. In loop.
To fix the issue, I just put the action "Set CB_Hash_Cycle to 1" first before generating the second hash.Here is the capx I've reproduced
I can't explain for sure what changed, this would be a question for @Ashley, but apparently, I don't think it's related to the plugin (unless I handled badly the triggering part).
