Invalid solid removes every entity from map [FIXED] I'm near to release beta 2 of frostfell and now I've hitted a new obstacle. When I load my map it says it has 2 invalid solids. So of course I let the hammer to delete them and save the file. After this hammer crahses and I try to reopen the file. On reopening this saved file I get the error: Orphane objects were found and placed into the "_orphaned hidden" visgroup. Clicking OK reveals that it has lost all Entities from the map. I think I could prevent this orphaned objects part if I could locate the 2 invalid solids from original file. Any idea how to find these? Or should I do something else? ------------ SOLUTION that worked for me: I realized that the hammer will fix the invalid solids no matter if it crashes so I downloaded a program that can compare two separate files and tell the differences. I knew that my invalid solids were the ones in skybox I created yesterday and with transfering data from file to file I could pinpoint the error causing lines. Using WinMerge to compare the files I noticed that almost all the lines were couple of rows off so I could search the missing rows. I copied 135 540 lines and pasted them over 146 507 lines. This seemed to fix it and opening the new edited file I noticed half of my skybox was moved to "orphaned visgroup" so I just deleted it as it wasn't needed anymore (it was just for reference).
