2 days ago, I update my all source code with «git fetch». Then I try to make changes on my smart contract.
I added 1 more action to *.cpp file. then generated related files. After then I typed «cleos set contact ….»
But it showed «error result is account.code_version != code_id:contract is already running…»
Finally I resolved this with adding «print statement in the action which was already exist.
Is this known bug? or some specific case? This is also 100% reproducible in hello world contract example.
