I’ve been editing a project over the weekend. Just after finishing with the third umap, I went back to an earlier one and it won’t open any longer.
The last things I was doing before the end was copying a group of particle systems from RoomTwo (the now crashing map) to the other (RoomThree), then I attempted to take level blueprint code from RoomTwo related to those particle effects. The references didn’t update and were just showing “Unknown” so I deleted them and wired things manually with references from RoomThree manually.
When I went back to switch to RoomTwo again, everything crashed, and continues to crashes unreal every time I try to open it or even when I right click the map to migrate it. Both of my other rooms work fine.
Hi, I might try that, though I found that there’s a bunch of saved backups in the Saved folder, and using one of those saves for RoomTwo seems to work with just a little lost progress. Thanks for the response though!
