Ah, ok, thanks, I had to go to "my assets" in the launcher menu. I thought it should be elsewhere.First download that scene via the launcher and after completed the downloading then goto destination of the downloaded file and find the .cryproject file,right click on it and click on switch engine version.It will ask you to change it to cryengine 5.5.x or the version of your sandbox and click ok to proceed.Now that project is can be opened in latest version.Lets us know if it works!
The editor is so crashy... wow. 3 minutes of exploring a room and bam - crash. What would happen if I had a big level? I hope it does not corrupt the level files
correction: this asset has got its own code, so crashing is normal on my newer version of Cryengine I guess.
