We may have to track down the cause, so if you can help, it's most welcome :). For that I can explain you the process as it is today: 1st) We previously exported all code from Pharo to FileTree (Metadataless I think). This step is not done anymore. 2nd) We bootstrap from the packages on FileTree by first compiling methods without metadata. 3rd) We export all bootstrap packages from filetree to MCZ https://github.com/pharo-project/pharo/blob/development/bootstrap/src/Pharo30Bootstrap.package/PBBootstrap.class/instance/exportAllPackagesIntoMcz.st 4th) Once the first image is ready (without source code nor meta-data) we install monticello and we reload all mcz files This regenerates the source code and should load all metadata in mczs https://github.com/pharo-project/pharo/blob/development/bootstrap/scripts/02-monticello-bootstrap/02-bootstrapMonticello.st So either it is that the metadata is lost in Filetree because it is metadataless, or it is lost in the intermediate conversion to mcz, or in the loading.
