Hi.

At some point of making a game I started receiving the warning on my Level04Gym\_maponly.umap:

```
Failed to patch linker table for blueprint CDO Default__SKEL_Level04GymLow_maponly_C
Failed to patch linker table for blueprint CDO Default__Level04Gym_maponly_C

```

What does it mean? How can I fix it?

Nope… But It looks like it doesn’t do any harm anyway…
