Hello,
I have come across this issue for the first time where few issues in one project are missing the Workflow button and I cant even drag them from one staus to another. we are in 6.4.12 version.
I tried to change the issue type and bring it back to original issue type. That didnt help and after researching I found that republishing of workflow helps. but havent tried that. and someone could let me know how I can do that without interuppiting other projects that share the same workflow will be a great help.
Thanks
