The reason caused the issue is that vela-cli will clean the step status when restart workflow, while workflow controller cached the step status count in memory and compare the count before reconcile, if the count is smaller than last cached count, it will skip reconcile. I'm confused about the step status count cache, is it still necessary?
here is the related code in workflow controller

workflow/pkg/executor/workflow.go

Line 130 in 9d55737

if cacheValue, ok := StepStatusCache.Load(cacheKey); ok {

This cache was originally used to handle the cache update problem caused by controller reconcile, it's an occasional problem so I'm no sure if we should disable it.
