Since there are a few players that may still have an older version (v1.08) of the sewing machine installed and placed in their saves I wanted to make note to delete it and make sure to clean up after the machine using Master Controller.
If you have v1.0.8 of the sewing machine installed and placed in any of your houses you may need to do a little cleanup when you delete it from the house you have it in.
This is due to the sewing machine not cleaning up after itself and may leave projects behind. You're looking for anything that is sewable rugs, beanbag chair, clothing items, teddybear etc.
Steps to cleaning up after deleting the machine:
With an active Sim, click on lot > Nraas MasterController > Object Stats > Not in Inventory
Select Unwanted objects to delete. Once chosen you can delete them individually or all at once.
If not cleaned up it could have the potential to corrupt the house. I've had this happen. I was able to fix it with the steps above.
Once cleaned up use Save As and save with new name.
If you have an even older version, it may still need to be deleted and cleaned up after. I just want to give a heads up.
The newer version while still buggy, is better. Creator is working to squash as many bugs as possible to hopefully make it more enjoyable to play with.
