Well, I did some testing today - and it all worked. So happy day - I now have no excuse not to fix these.....I will do some other small fixes while I am at it.
How to fix:
- If it's a simpack, run through Delphy's package extractor - make a package
- Open new project in TSRW
- Import from the package version of your file
- Give it a name when it asks - does not matter what
- Save as project
- Go to tools-project contents
- Select all in the list and delete
- Still in project contents, hit import from package and import all resources from your original package file
- Do all your fixes
- Export to sims3pack format - give it the same name as the original
- Extract using package extractor, give package same name as original
- Done. Publish to your sharing site of choice.
