The original installer's version is 12.6.03, while the reissued installer is version 12.6.06. Reissued installer has a bug which can be fix by changing 12.6.06 to 12.6.03 in Info.plist -file.

sudo plutil -replace CFBundleShortVersionString -string "12.6.03" /Applications/Install\ macOS\ Sierra.app/Contents/Info.plist

After this fix the creation of bootable installation disk should work.

Info was found online but not very easily. I hope this will reach more people. All credit to EricFromCanada's post
