Cloning project causes errors

Hi all,

I’m thinking of upgrading my 4.12 project to 4.13, so thought I would clone it first and run a quick test… selected clone, received a warning about renaming which I didn’t do (I obviously chose a new path but the project remained the same name). Cloning went fine with no visual issues.

Started the cloned version and it has issues with a couple of BPs… just wondering why this would be?? Any thoughts?

Error seems to be mainly with my BP_MM2_Environment, + one other out of pic.

Any ideas greatly received as I don’t want to attempt a project version update without running a full test.

Cheers,
Matt.
