@SpecZynk Unfortunately, this didn’t work for me. Any other ideas? I didn’t rename or move the struct, but I did try renaming it after I couldn’t resolve the issue. The issue still persists after renaming the struct and creating a new data table asset. Every time I relaunch the editor, the data table loses the reference to the struct. It’s also worth noting that the editor still sees the struct as I can create a new data table and point it to the same struct. I’ve also tried wiping the cache folders and rebuilding.
UPDATE: I forgot to wipe the plugin cache folders where the struct actually resides, but that didn’t work, either.
UPDATE 2: It appears to finally have sorted itself out? I purged cache folders again, and did a clean/rebuild of the projects. So far so good. I also applied the change mentioned here to hopefully avoid having this happen, again. Basically, enabling the “Force Compilation on Startup” option. Others seemed to have success with it, so hoping for the same.
UPDATE 3: Things seemed fine after a couple of restarts, but it has started happening, again. I’m on 5.5.3
UPDATE 4: Finally fixed it! Thanks to this post, I realized that I needed to change the LoadingPhase of my plugin from “Default” to “PreDefault” (or earlier).
