The message log just keeps posting this

This will just keep going, i have absolutely no idea what it means, not sure how its going to affect my build, i’ve seen some people fail to build their project and get this message.
I’ll soon find out though, any idea what is going on.

This is a blueprint only game, no C++

Hi insideitall,

You said this is only appearing in the Message Log? Have you received any sort of crash or any other odd behavior?

3

No crashes, i’m going to try and build the project and see if its anything that needs worrying about.

4

Okay, just post back here with your results. I haven’t been able to find another users outside of a code based project with this error.

Hi insideitall,
